Web- The solubility of the alkaline earth metal sulphates is slightly increased by the addition of strong acids. The more soluble the metal sulphate, the greater is its increase in solubility on addition of a strong acid. Thus, while the solubility of BaSO 4 is only slightly greater in acidic solution than in water, the solubility of CaSO 4
