Solubility: Gypsum Is moderately soluble in h2o, which has a solubility of about two grams per liter at twenty five°C. Interestingly, gypsum exhibits retrograde solubility, indicating its solubility decreases as drinking water temperature boosts – contrary to most salts that become much more soluble in hot h2o.
