At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. 2NACIO3→ 2NaCI + 302 A 0.8758 g sample of impure sodium chlorate was heated until the production of oxygen as ceased. The oxygen gas collected over water occupied 57.2 mL at a temperature of 22 °C and a pressure of 97858.6 Pa. Calculate the mass percent of NaClO3 in the original sample. (At 22 °C the vapor pressure of water is 19.8 torr) At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. 2NACIO3→ 2NaCI + 302 A 0.8758 g sample of impure sodium chlorate was heated until the production of oxygen as ceased.
