Chromium Chlorate, Cr(ClO₃)₃

Chromium Chlorate, Cr(ClO₃)₃, which is obtained by the double decomposition of barium chlorate and chrome alum, forms a violet solution which becomes green at 65° C. and decomposes on boiling, yielding chromium hydroxide and oxides of chlorine. The decomposition is facilitated by potassium ferricyanide. The salt is used in calico printing and for increasing the permanence of aniline black.
