From potassium chlorate
A mixture of potassium chlorate (KClO 3 ) and manganese dioxide (MnO 2 ) (4 : 1) is heated in a dry test tube. The oxygen evolved is collected over water. The decomposition of KClO 3 is accelerated even at lower temperatures as MnO 2 acts as a catalyst...

When Potassium chlorate is heated strongly it decomposes to give oxygen. But if a catalyst like manganese dioxide is mixed with it, oxygen is liberated at much lower temperature, in much shorter time. Potassium chlorate and manganese dioxide are mixed in the ..
