Calcium Bromate, Ca(BrO₃)₂.H₂O

Calcium Bromate, Ca(BrO₃)₂.H₂O, is obtained by the neutralisation of bromic acid with either the hydroxide or the carbonate of calcium, or by the electrolytic oxidation of calcium bromide. It forms mono- clinic crystals isomorphous with strontium and barium bromates. It is soluble in an equal weight of cold water. At 180° C. the bromate loses its water of crystallisation, and at a still higher temperature it gives up oxygen and forms the bromide. The density of the bromate is 3.329.
