The solubility of calcium sulphate in sodium chloride and sea salt solutions

Abstract The results of experiments on the solubility of calcium sulphate in sodium chloride solutions and in simulated sea water solutions at temperatures of up to lOO°C are given. They are compared with those of similar experiments by other workers and found to be in satisfactory agreement. A tabulation of the best molal solubility products of CaSO 4 anhydrite in sea salt solutions for the temperature range from 50° to 200°C is given in the appendix.
