Question

What happens when gypsum is heated above 373k

Answer 1

Answer: It forms Plaster of Paris.

Explanation:

Gypsum is a compound known as calcium sulfate bihydrate and when it is heated to 373K, it looses its water of crystallization and forms a compound named calcium sulfate hemihydrate. The compound formed is commonly known as Plaster of Paris.

The compound formed is used in the treatment of fractured bones in the hospitals.

The equation for the heating of gypsum at 373K is given by the equation:

$CaSO_4.2H_2O\overset{373K}\rightarrow CaSO_4.\frac{1}{2}H_2O+\frac{3}{2}H_2O$

Answer 2

When gypsum is heated above 373k Plaster of Paris is formed.

Explanation:

Gypsum is the compound which is known as calcium sulfate bihydrate. When 373k of heat is provided to the compound, it forms the compound known as calcium sulfate hemihydrate. When it is heated, the water of crystallization present in the compound is lost, resulting in the formation of a new compound. The compound that is formed is termed as the Plaster of Paris.
