Strontium Bromate, Sr(BrO₃)₂

Strontium Bromate, Sr(BrO₃)₂, may be obtained by dissolving strontium carbonate in bromic acid. It is also produced by the action of bromine on a hot solution of strontium hydroxide, but it is difficult to separate from the bromide, which is formed at the same time. It crystallises in rhombic prisms as the monohydrate, Sr(BrO₃)₂.H₂O, isomorphous with barium chlorate and of density 3.773, but loses its water at 120° C. It begins to decompose at 240° C., losing oxygen and bromine, and leaving a residue of strontium oxide and bromide. It is soluble in three times its weight of water.
