Barium Chlorite, Ba(ClO₂)₂

Barium Chlorite, Ba(ClO₂)₂, is formed by the action of chloric acid on barium hydroxide in solution. It is an unstable salt, but it can be obtained in a fairly pure condition by rapid evaporation over a flame until a skin is formed, and then further concentration in vacuo. Slow evaporation results in the formation of the chlorate. Barium chlorite is very soluble in water, and is decomposed into chlorate and chloride at 235° C.
