Question

explain the preparation of plaster of Paris with the help of balanced chemical equation my​

Answer 1

Plaster of Paris is also known as Calcium sulphate hemihydrated salt with chemical formula CaSO4.1/2H2O

Preparation method :

Plaster of Paris is prepared from  gypsum.

Gypsum is heated to a temperature of 100⁰c . It looses 3/ 4th of its water  of

crystallization  and forms Plaster of Paris.

Balanced Chemical equation:

CaSO4.2H2O-----> CaSO4 .1/2H2O + 3/2 H2O

mark it brainleist.

Answer 2

CaSO4.hemi hydrate+ mono hemi hydrate = caso4.2 hydrate

When the gypsum is heated on 373°k it convert into plaster of Paris  

CaSO4. 2H2O +energy 373°k =CaSO4. 1/2H2O+3/2H2O
