It is a typical salt, forming neutral aqueous solutions. Like all compounds of Sr, this salt emits a bright red colour in a flame; in fact it is used as a source of redness in fireworks. Its chemical properties are intermediate between those for barium chloride, which is more toxic, and calcium chloride. ==Preparation== Strontium chloride can be prepared by treating strontium hydroxide or strontium carbonate with hydrochloric acid: :Sr(OH)2 + 2 HCl → SrCl2 + 2 H2O Crystallization from cold aqueous solution gives the hexahydrate, SrCl2·6H2O. Dehydration of this salt occurs in stages, commencing above . Full dehydration occurs at .〔J.
