Solubility figures for magnesium sulfate and calcium sulfate also vary depending on whether the salt is hydrated or not, but the variations are less dramatic. 7,955 8 8 gold badges 43 43 silver badges 92 92 bronze badges. Dutrizac. Maddahi, M.S. The Canadian Journal of Chemical Engineering. Solubilities and supersaturations of calcium sulfate and its hydrates in seawater. Calcium was determined as Cao after precipitation as CaC03 and sulfate as BaS04' The values given are means of 2 - 13 measurements which differ by up to 10%. Understanding of the solubility of calcium sulfate (CaSO4) is essential to controlling scale formation in cooling water systems. Removal and utilization of calcite existed in scheelite by preparation of calcium sulfate whiskers. No available data.
