Solubility: Gypsum Is reasonably soluble in h2o, by using a solubility of about 2 grams for each liter at twenty five°C. Apparently, gypsum displays retrograde solubility, this means its solubility decreases as water temperature raises – not like most salts that develop into much more soluble in incredibly hot water. https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
