Solubility: Gypsum Is moderately soluble in water, with 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 will increase – not like most salts that grow to be far more soluble in very hot water. https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
