Solubility: Gypsum Is moderately soluble in h2o, using a solubility of about two grams for each liter at 25°C. Curiously, gypsum exhibits retrograde solubility, this means its solubility decreases as drinking water temperature increases – contrary to most salts that develop into more soluble in incredibly hot drinking water.
