Bismuth Chlorate

Bismuth chlorate does not appear to have been isolated, for although bismuth hydroxide dissolves readily in dilute chloric acid, the solution decomposes on concentration. When a hot aqueous solution of bismuth nitrate and sodium chlorate is cooled, long, glistening prisms of bismuthyl chlorate, BiOClO₃, separate. This substance does not appear to react when warmed with either carbon or a mixture of carbon and sulphur; but it detonates on heating with potassium cyanide.
