Question

How is plaster of Parish prepared? Write chemical equation of the reaction involved.

Solution

When gypsum (CaSO4.2H2O) is heated to a temperature of 100C (373K), it loses three-fourths of its water of crystallisation and forms plaster of Paris. ​

CaSO4.2H2O Δ → CaSO4.1/2H2O + 3/2 H2O

 Gypsum           Plaster of Paris
