Manganese dioxide is used during preparation of oxygen from potassium chlorate. Why?

Answers

Answered by Anonymous

Because it involves the catalytic decomposition of potassium chlorate to potassium chloride and oxygen. The catalyst in question is manganese dioxide. This reaction can be carried out in an ordinary test tube, and if you've got a hose and one-holed stopper, oxygen is yours.
