Question

Define the term water of crystallization. How can a hydrated salt be converted into anhydrous
salt?​

Answer 1

Answer:

The number of water molecules a unit of salt molecule holds is known as water of crystallization . example - CuSO4.5H2O

hydrated salts can be converted into anhydrous salts by heating

Explanation:

water of crystallization imparts color to the salt.  CuSO4.5H20 is blue in colour. when it is heated , it loses the water molecules it holds and turns into white / dirty white. also anhydrous salts undergo exothermic reaction instead of endothermic reaction like the hydrated salts

CuSO4.5H2O -----------> CuSO4 + 5H2O
