Question

give reasons why plaster of paris is not heated beyond 373k​

Answer 1

Explanation:

When gypsum is heated at 373 K, it loses its water of crystallization or all the water molecules and becomes calcium sulphate hemihydrate. Gypsum is converted to “Plaster of Paris”. On being further heated beyond 373 K, gypsum gives a product known as Gamma “Anhydrite”.

Answer 2

Answer:

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

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.
