Answer

The compound you are referring to is plaster of Paris. It is prepared from gypsum, which is chemically known as calcium sulfate dihydrate (CaSO₄·2H₂O).

Preparation:

The chemical equation for the preparation of plaster of Paris from gypsum is:

CaSO4⋅2H2O + heat → CaSO4⋅½H2O + 3/2H2O

Use in Hospitals:

Plaster of Paris is commonly used in hospitals to make orthopedic casts for immobilizing broken bones. When mixed with water, it hardens and forms a solid structure that helps in the healing process.
