______________________________

the name plaster of Paris. came from that fact it was first of all made by heating gypsum which is mainly found in Paris..

it is commonly known as P.O.P.

______________________________

Chemical equation:

........................... heat to(100°c)

2(CaSO4.2H2O)-------------------->

2CaSO4.H2O. + 3H2O.

here reactant is gypsum.

it is heated on temperature 100°c.

then product obtained is plaster of Paris and water.

Precautions.

→ in the preparation of plaster of Paris heating of gypsum should be controlled carefully.

→ the temperature during the heating of gypsum should not be allowed to go above 100° c.

→ this is because if the gypsum is heated above 100 degree Celsius then its water of crystallization is eliminated and anhydrous calcium sulphate (CaSO4) called dead burnt plaster is formed.

→ The anhydrous calcium sulphate does not set like plaster of Paris on adding water.
