Solubility: Gypsum Is reasonably soluble in h2o, having a solubility of about 2 grams for every liter at twenty five°C. Apparently, gypsum reveals retrograde solubility, that means its solubility decreases as h2o temperature increases – in contrast to most salts that become more soluble in hot h2o.
