Sodium chlorate is a chemical compound with the chemical formula (NaClO3). When pure, it is a white crystalline powder that is readily soluble in water. It is hygroscopic. It decomposes above 250 °C to release oxygen and leave sodium chloride.

III.           Synthesis

Industrially, sodium chlorate is synthesized from the electrolysis of a hot sodium chloride solution in a mixed electrode tank:

NaCl + 3H2O → NaClO3 + 3H2

It can also be synthesized by passing chlorine gas to a hot sodium hydroxide solution. It is then purified by crystallization.

IV.             Application

The main commercial use for sodium chlorate is for making chlorine dioxide, ClO2 and medical agent.

The largest application, approx. 90% of the sodium chlorate, is in bleaching of pulp where chlorine dioxide today is the predominant bleaching agent.

Recently it is more increasingly widely used as water treatment agent, fireworks agent and PCB etching solution.
