Abstract
A process for making a dry metal halide salt which will not form an insoluble flocculent material upon dissolving in water in which an initial aqueous solution of a metal halide salt is prepared and a member selected from the group consisting of ammonium chloride, ammonium bromide, borate anion producing compounds and mixtures thereof is added. Water is then evaporated from the initial aqueous solution and a dry metal halide salt is obtained. Upon dissolving this dry metal halide salt in water a clear, colorless solution results which does not contain an insoluble flocculent material. Alternatively, the member compound may be added to the dry metal halide salt, before it is dissolved in water or the member compound may be added to the water which is used to dissolve the dry metal halide salt.
