Potassium Sulfate

Most gypsum products are obtained from natural gypsum rock. Because gypsum is the dihydrate form of calcium sulfate (CaSO 4 · 2H 2 O), on heating, it loses 1.5 g mol of its 2 g mol of H 2 O and is converted to calcium sulfate hemihydrate (CaSO 4 · ½H 2 O), sometimes written (CaSO 4) 2 · H 2 O. When calcium sulfate hemihydrate is mixed with water, the reverse reaction takes …
