Solubility: Gypsum Is reasonably soluble in h2o, which has a solubility of about 2 grams for every liter at 25°C. Interestingly, gypsum displays retrograde solubility, that means its solubility decreases as drinking water temperature raises – compared with most salts that turn into much more soluble in incredibly hot water. https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
