Is calcium sulfate soluble in sulfuric acid? The published solubility data of calcium sulfate hydrates in sulfuric acid solutions were collected and reviewed critically. … However, at temperatures above 398.15 K and sulfuric acid concentration above 0.5 mol/kg, the solubility of anhydrite predicted by our model deviates significantly from the literature data.
Does calcium sulfate react with sulfuric acid? The reaction of sulfuric acid with calcium metal produces a coating of calcium sulfate (CaSO4) on the metal. Since the calcium sulfate is insoluble in water, the coating acts as a protective layer thus preventing further attack on the metal by the acid.
