Percentage of Oxygen in Potassium Chlorate Introduction: The thermal decomposition of potassium chlorate can be described by the following equation: 2 KCIO3(s) 2 KCls) + 3 O2(g) Egn 1 (D stands for heating, elevated temperature) In this experiment you will determine the percentage of oxygen in potassium chlorate. You will compare the experimental result with the theoretical percentage calculated from the formula KCIO3. While potassium chlorate decomposes simply by heating, the reaction is very slow. A catalyst is used. Catalyst...
