Question

Write the name of the products formed by heating gypsum at 373K? Write one use of it.

Answer 1

The chemical formula of Gypsum: CaSO₄.2H₂O

When gypsum is heated at 373k, we get plaster of Paris

Chemical equation: 
                            Δ
CaSO₄.2H₂O  ---------->CaSO₄.1/2H₂O  +3/2 H₂O

So, Calcium Sulphate Hemi hydrated salt --- CaSO₄.1/2H₂O is produced after heating gypsum.

Plaster of paris is used in case of fracture.
