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.
