Use of a standard commercial calcium solution, 1 g/L, is preferred. Alternatively this solution may be prepared by dissolving 2.5 g of calcium carbonate, CaC03, in sufficient hydrochloric acid (concentrated hydrochloric acid diluted 1:10) to dissolve it completely and making up to one liter with distilled water.
