Solubility: Gypsum Is reasonably soluble in h2o, which has a solubility of about 2 grams per liter at twenty five°C. Curiously, gypsum reveals retrograde solubility, indicating its solubility decreases as h2o temperature will increase – in contrast to most salts that grow to be extra soluble in scorching h2o.
