plaster of parisplasterofparis

[calcium sulphate hemihydrates]

[CaSO4. 1/2H2O]

on heating gypsum [CaSO4. 2H2O] at 373K, it loses water molecules and become plaster of Paris [POP].

it's is white power and on mixing with H2O it changes to gypsum

CASO4. 1/2H2O + 1X 1/2 H2O -------CASO4. 2H2O.

USES
