Potassium chlorate and sugar initiated by Conc. Sulfuric acid

None of the above experiment should be repeated on your own.
Welcome to C For Chemistry
Potassium chlorate and sugar react exothermically due to Potassium chlorate oxidizing nature, and high energy value in sugar.
They are stable at Room Temperature Pressure but a little activation energy is sufficient to initiate the reaction.
Concentrated Sulfuric acid reacts with Potassium chlorate producing Chlorine dioxide, which is a very reactive species.
Chlorine dioxide is then reacted with sugar providing the activation energy.
Once the reaction is initiated lilac flame is observed due to presence of Potassium ion.
Concentrated Sulfuric acid acts as a medium for the reaction.
Producing flame that could react 2000 Kelvin which the crucible may crack.
This reaction should be performed in ventilated area with fire extinguisher nearby.
