Answer 2

Below mentioned are the reasons why Plaster of Paris should be stored in moisture-proof container -

Explanation:

• Plaster of Paris is a well known substance that is used most commonly for sculpting materials and in gauze bandages.

• Plaster of Paris is also referred to as Gypsum plaster. The chemical formula of plaster of Paris is written as $CaSO_{4}.H_{2}O$

• Since moisture can affect the plaster of Paris by slowing the setting of the plaster due to hydration, it should be stored in a moisture-proof container.

• The plaster will be rendered worthless as a result of this.

• Plaster of Paris is calcium sulphate, and when the water of crystallization is added to it, gypsum is formed, which is a hard material.

• So plaster of Paris should be stored in a moisture proof, sealed container.
