Solubility: Gypsum Is reasonably soluble in drinking water, having a solubility of about 2 grams per liter at 25°C. Interestingly, gypsum reveals retrograde solubility, that means its solubility decreases as h2o temperature increases – not like most salts that turn out to be far more soluble in very hot drinking https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
