Is prepared by dissolving natural carbonate of strontium in hydrochloric? acid. Long, colorless needles, easily soluble in water and also in strong alcohol; absorbing moisture on exposure. Dry strontium chloride prepared from it is a white powder, and frequently employed in the combination of artificial mineral waters to produce by mutual decomposition the components carbonate or sulphate of strontium. It is kept in solutions of ten or one per cent.
One part in nine parts of distilled water (10 per cent.), specific gravity 1.092; or one part in 100 parts of distilled water (one per cent.), specific gravity 1.009 at 15° 0. The latter solution is preferable as the diminutive quantities required are better measurable. Proportion 10 to 1 (10 per cent.) or 100 to 1 (1 per cent.).
