Strontium chloride (SrCl 2) is a salt of strontium and chloride. 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.he solid adopts a deformed rutile structure. In the vapour phase the SrCl 2 molecule is non-linear with a Cl-Sr-Cl angle of approximately 130Â°. This is an exception to VSEPR theory which would predict a linear structure.
