In this lab, students will test the percent composition of KClO3.

"Potassium chlorate is one of several compounds of oxygen that are easily decomposed by heating. Potassium chlorate will decompose into oxygen and potassium chloride. In this laboratory exercise you will decompose this compound by heating, and from the data obtained determine the percentage of oxygen by weight in the compound."
