Formation of another hydrate by hydration

Vedclass · Answer

(D) Plaster of Paris is $CaSO_4 \cdot \frac{1}{2}H_2O$. When it is mixed with water,it undergoes hydration to form a hard solid mass known as gypsum $(CaSO_4 \cdot 2H_2O)$. The reaction is: $CaSO_4 \cdot \frac{1}{2}H_2O + \frac{3}{2}H_2O \rightarrow CaSO_4 \cdot 2H_2O$. Thus,the setting of Plaster of Paris is due to the formation of another hydrate by hydration.

The setting of Plaster of Paris is associated with which of the following?
