Question

Can I use plaster of paris on walls?

Answer 1

Plaster of paris $\left({\mathrm{CaSO}}_4.\frac{1}{2}{H}_{2}O\right)$:

1. Plaster of paris is a white powdery chemical compound obtained from calcining gypsum.
2. It is used as a sculpting material.
3. When water is added to plaster of paris, the gypsum present in it crystallises and solidifies to give a firm structure.
4. Hence, plaster of paris can be used on walls.
