Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant . One particular hydrate is better known as plaster of Paris , and another occurs naturally as the mineral gypsum .

Ca(OH)2 + H2SO4 >> CaSO4 + 2H2O. i believe the balanced equation is: H 2 SO 4 + 2KOH --> K 2 SO 4 + 2H 2 O because there have to be the same number of atoms on each side of the equation.

CaSO 4.1/2H 2 O is just a simplified way of writing. Cheers!! 0 ; View Full Answer. The Actual formula of pop is 2CaSO 4 that means for every 2 molecules of calcium sulphate is one molecle of water and if this formula is further simplified we get CaSO 4.1/2H 2 O .
