can anyone explain me plaster of paris ??

Dear Student,

Please find below the solution to the asked query:

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 hemihydrate. Its chemical formula is CaSO₄.1/2H₂O. Following is the chemical equation for the reaction

Hope this information will clear your doubts about the topic.
