Question

Explain the process of making Plaster of Paris??​

Answer 1

Answer:

Plaster of paris is made from gypsum ( CaSO₄·2H₂O)

Explanation:

Plaster of Paris is made by heating gypsum crystals which results in it losing the 2 water molecules thereby forming Plaster of Paris.

CaSO₄·2H₂O⇄CaSO₄·1¹/₂H₂O+¹/₂H₂O  [In presence of heat]

[I used those arrows as this gypsum can be remade from Plaster Of Paris

Answer 2

Plaster of Paris is manufactured by heating gypsum at 373 – 393 K or 150° C/300° F. On heating gypsum at 373 – 393 K, it loses water molecules and becomes calcium sulphate hemihydrate. This product is known as the plaster of Paris. However, when water is mixed with dry plaster of Paris, it re-structures into gypsum.
