#KClO_3(s) + Delta rarr KClO(s) + O_2(g)uarr#


With suitable catalysis, #KClO# can be further reduced to #KCl#, and more oxygen given off. It is thus a convenient source of oxygen gas that you don't have to store in a bottle. Potassium chlorate is present in many fireworks, and some very zippy experiments can be done in the lab.
