Reaction of Plaster of Paris and water
The chemical equation for the reaction of Plaster of Paris and water can be represented as
CaSO4.1/2H2O + 3/2H2O → CaSO4.2H2O
As plaster of Paris reacts with water, heat is released through crystallisation. Gypsum is made by heating plaster of Paris to about 150 degrees Celsius. As water is added to dry plaster of Paris powder, it reforms into gypsum. Gypsum transforms to hemihydrate or anhydrous form depending on the temperature.
