    Plaster of Paris

    Ans: Calcium sulphate hemi hydrated is commonly known as "plaster of Paris". Chemical formula: /2H2O. Plaster of Paris is prepared by gypsum. When gypsum is heated up to 100 0 C,it loses some molecules of water of crystallization and forms an amorphous white solid known as plaster of Paris. Plaster of Paris when mixed with water sets ...
