Q.13: Plaster of Paris should be stored ion a moisture-proof container. Explain why.

 

Answer:-

Plaster of Paris easily absorbs water and forms hard gypsum. Thus, if Plaster of Paris is not kept in a moisture-proof container, then all Plaster of Paris will get converted into gypsum.

CaSO4.½H2O + 1½H2O –> CaSO4.2H2O
