Question

Explain action of heat on hydrated salts with the help of a example

Answer 1

Answer:

When hydrated salts are heated the water content is lost, ie., water of crystallisation is lost and forms powder. Thus, we can say that hydrous salts becomes anhydrous. Also, there might be changes in the colour.

Eg.,

CuSO4 --> CuSO4 + H2O

This is a reversible reaction
