Solubility: Gypsum Is moderately soluble in drinking water, that has a solubility of about two grams for every liter at twenty five°C. Apparently, gypsum displays retrograde solubility, that means its solubility decreases as h2o temperature raises – contrary to most salts that turn into more soluble in very hot h2o. https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
