| 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. |
