Solubility: Gypsum Is moderately soluble in drinking water, which has a solubility of about 2 grams for each liter at twenty five°C. Apparently, gypsum reveals retrograde solubility, indicating its solubility decreases as h2o temperature increases – contrary to most salts that come to be more soluble in very hot water. https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
