Strontium Nitrate - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: 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.See our 24 reactions playlist as it unfolds at: Day explained: chemistry at us on Facebook at on Twitter at the School of Chemistry at The University of Nottingham: Videos films are by video journalist Brady Haran
