I added explanation in english to this vid. Use cc. In this vid I'll show you the exothermic reaction between potassium nitrate (KNO3) and sucrose/sugar (C12H22O11). I've used the ratio around 3:2 for KNO3:C12H22O11. It's an exothermic reaction. Some observations are: - The violet/purple flame: This is recognizable for the potassium particle. - The reaction products: KNO2 (yellowish) and K2CO3 (white) Where KNO2 has formed KNO3 was in excess and where K2CO3 has formed the sugar was in excess.
