Answer 1

Plaster Of ParisPlaster of paris is calcium sulphate hemihydrate. The chemical formula of Plaster of paris is CaSO4·½H2OIt is known as P.O.P.PreparationIt is prepared from gypsum.Gypsum is calcium sulphate dihydrate. The chemical formula of gypsum is CaSO4·2H2OPlaster of paris is prepared by heating gypsum to a temperature of 373K.When gypsum is heated to a temperature of 373k ,It loses three-Fourths of its water of crystallisation and forms plaster of paris.Properties1)It is a white powder.2)It has a very remarkable property of setting into a hard mass on wetting with water.P.O.P. should be stored in a moisture proof container.Uses1)It is used in hospitals for setting fractured bones in the right position to ensure correct healing.2)It is used in making toys,decorative materials,cheap ornaments,cosmetics,black-board and casts for statues.3)It is used in chemistry laboratories for sealing air gaps in apparatus where air-tight arrangement is required.4)It is used for making surfaces smooth before painting.
