Solubility: Gypsum Is moderately soluble in h2o, which has a solubility of about two grams per liter at twenty five°C. Interestingly, gypsum reveals retrograde solubility, meaning its solubility decreases as water temperature will increase – contrary to most salts that develop into additional soluble in warm water.
