how is plaster of paris formed mention the chemical equation of the reaction that takes place during the setting of plaster of Paris
Answers
Plaster of Paris is prepared by heating gypsum [which is chemically calcium sulphate dihydrate (CaSO4.2H2O)] at 373 K. On heating at 373 K, gypsum loses water molecules and becomes Plaster of Paris, which has the chemical name calcium sulphate.
On heating at 373 K, gypsum loses water molecules and becomes Plaster of Paris, which has the chemical name calcium sulphate hemihydrate. Its chemical formula is CaSO4.1/2H2O.
Explanation:
The chemical formula of plaster of Paris is CaSO4.1/2H2O. Plaster of Paris is prepared by heating gypsum (CaSO4.2H2O) to a temperature of 373 K in a kiln.Plaster of Paris is a white colour substance that becomes hard when come in the contact of water. it is prepared from the gypsum by heating it .
POP=Caso4.1/2H2O.
Calcium sulphate hemi hydrate.
it is prepared by heating the gypsum at 369 k of temperature.
this is stored in moisture proof container because it becomes hard when comes in the contact of water or moisture.
it is used for making statues and buildings.
it is also used to support fracture.
