Question

When copper sulphate is heated

Answer 1

Hello friend

___________________________

When copper sulphate is heated then it loses it's water of crystallisation to form white anhydrous copper sulphate sulphate.

The reaction are as follows:::

CuSO4•5H2O ==>heated=> CuSO4 + 5H2O

Means :

Copper sulphate (blue)==> heated=>White anhydrous copper sulphate + water.

Thanks..

Answer 2

Hello friend...!!

•Copper sulphate contains five molecules of water of crystallisation. When these blue crystals are heated the water molecules get evaporated and turns white in Colour.

• water of crystallisation is the fixed number of water molecule that is present in one formula unit of salt.

• copper sulphate has 5 molecules of water crystallisation.

CuSO4.5H2O======> CuSO4+5H2O.
