Periodic Videos

We're making a video about each element on the periodic table.

A special feature, with clips from each of our 118 element videos squeezed into 10 minutes. This was made to be shown at a local media centre in Nottingham, but we wanted to share it with YouTube also.

Hydrogen Balloon Explosion - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=6rdmpx39PRk NOTE FROM THE PROFESSOR: The main reaction is quite simple. 2H2 + O2 → 2H2O. However, the balloon is made from rubber, which is a complex molecule containing principally containing carbon and hydrogen. The heat of the hydrogen burning probably sets fire to the rubber generating CO2 and water. The orange colour probably comes from the burning rubber.

Potassium Permanganate Colour Change - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=OLUyeCC-2Ko NOTE FROM THE PROFESSOR: The colour change is caused by the purple permanaganate ions [MnO4]- gaining electrons to form colourless Mn(+2) ions. The oxygen from the permanganate and the H2O2 are converted to H2O and O2 (which bubbles off). The extra H atoms come from the sulphuric acid H2SO4. Both the K and Mn end up as sulfates.

Gold in Aqua Regia - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=iwnKU89CCdI NOTE FROM THE PROFESSOR: Aqua Regia is a really complicated mixture. The key point is that together HCl and HNO3 are more effective oxidizing agents than they are individually because they react together to form a variety of ions. These can then react with the gold, enabling it to lose electrons to form bonds with chlorine. The result is a solution a mixture of ions with different ratios of Au to Cl atoms. I still find the dissolving of gold a magical reaction to watch.

Calcium Carbide and Acetylene - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=KQSLpuVZK9Y NOTE FROM THE PROFESSOR: Calcium carbide reacts with water to form acetylene (also known as ethyne) and Calcium hydroxide. The fact that the water is present as ice doesn't matter. A combination of the heat of the reaction and the presence of salts causes the ice to melt and the reaction involves liquid water. See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Aluminium in Chlorine Gas - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=BXCfBl4rmh0 NOTE FROM THE PROFESSOR: Cl2 reacts with Al to form aluminium trichloride, which normally exists as Al2Cl6. In the high temperature of this reaction, things may be more complicated. See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Copper Sulfate Colour Change - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=kop1sWzTK-I NOTE FROM THE PROFESSOR: This reaction converts a blue solution of CuSO4 to a red precipitate of Cuprous oxide Cu2O. It does so be oxidizing the tartrate ion (which contains C, H and O) to CO2 and H2O. Therefore, there are not enough anions in the solution for both the Cu and K to exist as salts and the Cu is converted into its oxide See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Zirconium Powder in Flame - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=gNJE2MPktvg NOTE FROM THE PROFESSOR: The Zr reacts with oxygen in the air to make zirconium oxide in a very exothermic reaction (it gives out a lot of heat). The white light comes from very hot particles of the oxide. See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Caesium in Water - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=5aD6HwUE2c0 NOTE FROM THE PROFESSOR: The reaction is 2Cs + 2H2O → 2CsOH + H2. However, the H2 can then react with O2 in the air to explode. Also, unlike the other alkali metals, except perhaps Francium, Cs is a liquid just above room temperature so the initial heat of reaction will melt the metal and one has liquid metal reacting with the water. See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Potassium, Diethyl Ether and Water - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=z1z0AVvY9yM NOTE FROM THE PROFESSOR: This reaction is the same as that of K with water, 2K + 2H2O → 2KOH + H2. The difference is that diethyl ether floats on the surface of the water (it's less dense) and it has a very low boiling point so it's vapour easily catches fire to form CO2 and more H2O. Once it's burning, some of the K is vapourized and gives the flame a lilac colour. See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Fluorine Gas and Sulfur - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=vtWp45Eewtw NOTE FROM THE PROFESSOR: This is a very violent reaction so many things may be going on. In the molecular structure of solid sulfur, one finds S8 rings. At the simplest level, these react to form SF6; S8 + 48F2 → 8SF6. However, this reaction is involves a jet of F2 gas so there may not be enough fluorine and some SF4 may be formed. SF4 can react violently with water in the air to form SO2 and HF. In addition, the reaction heats the sulfur causing it to melt and the S8 molecules to break up forming longer chains of sulfur atoms which have a brownish colour. This hot sulfur can also react with O2 in the air to burn to form SO2.

Thermite Reaction - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=euQUgp5AY-Y NOTE FROM THE PROFESSOR: In this reaction aluminium is converted to aluminium oxide and iron oxide to iron. Al + Fe2O3 → Al2O3 + Fe. The interaction between Al and O is stronger than that between Fe and O so the reaction liberates a large amount of heat. See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Copper Chloride and Aluminium - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=OQPwPGDQqzs NOTE FROM THE PROFESSOR: 13. This is another dirty reaction. The simple explanation is that Copper chloride reacts with Al to make Cu plus aluminium chloride. And you can see the reddish colour of the metallic copper at the end. The reason that it's complicated is that Al chloride (Al2Cl6) can itself react with water to make Al2O3 plus HCl and the HCl can then react with the cupcake case See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Magnesium Burns in Carbon Dioxide - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=0dSMzg0UPPo NOTE FROM THE PROFESSOR: The Mg effectively extracts the oxygen from CO2. 2Mg + CO2 → 2MgO + 2C. Solid CO2 and MgO are both white but elemental Carbon is black. The reason why the reaction is so violent is that solid CO2 contains molecules of CO2 which interact weakly while solid MgO is made up of Mg(2+) and O(2-) ions which because of their charges interact very strongly giving out large amounts of energy as the solid MgO is formed. See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Diethyl Zinc in Air - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=99wPiMb-k0o NOTE FROM THE PROFESSOR: The compound burns to form zinc oxide, CO2 and Water; Zn(C2H5)2 + 5O2 → ZnO + 4CO2 + 5H2O See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Dinitrogen Tetroxide and Aniline - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=bin_W1xVPfY NOTE FROM THE PROFESSOR: This is the reaction of aniline, C6H5NH2, with N2O4. The products are N2, H2O and CO2. The reaction is violent because N2O4 has a very weak N-N single bond while N2 has a very strong N-N triple bond. The formation of C=O bonds in CO2 releases further energy. This reaction was discovered at Nottingham about sixty years ago; rumour has it that the student who discovered it was injured in the process!

White Phosphorus - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=U6_-EUcswSc NOTE FROM THE PROFESSOR: 9. White phosphorus is made up of tetrahedral shaped P4 molecules with very strained (and weak) bonds. P4 reacts with oxygen to make a white solid containing P4O10 molecules, which confusingly is called "phosphorus pentoxide" (it's confusing because "pent" is derived from the word "five" in Greek).

Cans in Acid and Base - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=WnPrtYUKke8 NOTE FROM THE PROFESSOR: In the UK, Coke cans (but not Pepsi) are made from aluminium. In HCl, the Al dissolves initially to form aluminium trichloride and probably after that H+ and [AlCl4]- ions. In NaOH, Al forms sodium aluminate See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7 Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4 More chemistry at http://www.periodicvideos.com/ Follow us on Facebook at http://www.facebook.com/periodicvideos And on Twitter at http://twitter.com/periodicvideos From the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspx Periodic Videos films are by video journalist Brady Haran http://www.bradyharan.com/

Strontium Nitrate - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=d5ztPGrsgNQ NOTE FROM THE PROFESSOR: This is a mixture of reactions. You can think of it as KClO3 first decomposing to KCl and oxygen. The sugar which contains C, H and O then burns to give CO2 and H2O plus a lot of heat. The heat probably decomposes or vaporizes the Sr(NO3)2 and generates some Sr atoms in the gas phase. These hot Sr atoms give out red light.

Full video containing this reaction at: http://www.youtube.com/watch?v=0XLGopBovoI NOTE FROM THE PROFESSOR: Rubidium reacts the same way are other alkali metals. 2Rb + 2H2O → 2RbOH + H2 and the hot H2 can burn/explode with O2 from the air.

Potassium in Water - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=pPdevJTGAYY NOTE FROM THE PROFESSOR: Potassium always seems to react particularly violently; 2K + 2H2O → 2KOH + H2. It may just be that we use bigger lumps of it or perhaps the melting point is just right for the metal to begin melting when the reaction is already going strongly.

Barking Dog chemical reaction - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=vsiPt3l6H3U NOTE FROM THE PROFESSOR: 4. The basic mixture is carbon disulfide CS2 plus nitrous oxide, N2O. The N2O decomposes and 2N2O → 2N2 + O2. This reaction needs heat to get it going but is then quite violent. The O2 Reacts with CS2 to make a mixture of CO2, SO2 and solid sulfur. Some of the sulfur and SO2 are formed in a so-called excited state (with a big excess of energy) and the energy is lost by emission of blue light.

Fluorine Gas and Charcoal - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=vtWp45Eewtw NOTE FROM THE PROFESSOR: This is again a complex reaction. On the simplest level F2 reacts with C for form CF4, the fluorine analogue of methane, CH4. However, the carbon gets very hot and probably some of it burns in air to make CO2. Also at these high temperatures other C/F compounds such as C2F6 as probably formed.

Calcium Chloride in Bunsen Flame - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=V9fuY8_ffFg NOTE FROM THE PROFESSOR: If you heat salts in a bunsen flame you varpourize some of the metal ions, in this case Calcium and some of the atoms have excess energy which they emit as light at particular wavelengths characteristic of that element. For Calcium this light is red but, as Debbie says, her sample of CaCl2 may have had some traces of NaCl in it. Na gives off yellow/orange light (you can see it in some street lamps) and Na is more volatile than Ca so even a little in her sample could nearly swamp the colour of the calcium in the flame.

Cheeseburger in Hydrochloric Acid - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=NddZ5ftQb0Q NOTE FROM THE PROFESSOR: This reaction is a big mess, which is why it looks so funny. The underlying chemistry is hydrolysis (reaction of an organic compound with water) which is catalysed by the acid. The starch in the bun is hydrolysed to make first sugars (such a glucose) and then a complicated mixture of breakdown products. The fats in the cheese and the meat are probably hydrolysed too. The physical structure of the meat will be destroyed and some of the proteins will be denatured (their folding is disrupted) if not actually broken down. In the end, it's probably better just to enjoy the reaction than to worry too much about the chemistry. Just have fun!!

Learn more at http://www.google.com/chromecast NOTES 1. Music by Alan Stewart - Alan played the music in one take while watching the video for the first time! Alan: http://www.youtube.com/user/AlanKey86 2. The ethanol demonstration was intended to show the liquid would burn without damaging the object we doused. We chose a currency note because everyone is familiar with it - knows what is made from, feels like, etc. And they would know it is not a trick substance. There was no intent no cause any damage - just educate and entertain. You can bid on the $50 in our charity auction... http://www.ebay.co.uk/itm/380797103246 3. The Potassium Nitrate - which also didn't go the plan - was designed to reveal a message on the paper - you should still be able to see it! (periodic videos loves to share all our demonstrations with you - even when they don't quite work or fail completely - you can learn much from so-called "failures") 4. The video was filmed in Neil's fume hood - where else?
