Potassium Chlorate and Sugar ignitor

  1. May 4, 2005 #1
    In a Potassium Chlorate (a strong) oxider and sugar is mixed with sulfuric acid a fire will break out. I understand that a acid-strong oxdizing reagent is exothermic reaction but why the sugar required.

    I think the acid is only meant to get the Chlorate sugar reaction started.

    Yes, the proper question should probably be "Why is sulfuric acid required" as a catalyst. I imagine the mechamism is very similiar to that involved in the dehydration of alcohols, though I am not 100% positive.

    It reacts with the chlorate releasing heat to get it started.

    The KClO4 is the oxidiser and sugar is the fuel
