Solubility: Gypsum is reasonably soluble in h2o, with a solubility of about two grams for each liter at 25°C. Apparently, gypsum displays retrograde solubility, meaning its solubility decreases as water temperature increases – in contrast to most salts that come to be a lot more soluble in sizzling drinking water. https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
