Question
Give balanced equation for the following conversion affected by heat alone on the substance:
Hydrated copper sulphate to sulphur dioxide
Solution
Action of heat on:
\[\ce{\underset{\text{[Hydrated copper sulphate blue]}}{CuSO4.5H2O} ->[\triangle]\underset{\text{[Anhydrous white]}}{CuSO4} + 5H2O}\]
On Strong heating:
\[\ce{\underset{\text{[white]}}{2CuSO4} ->[\triangle]\underset{\text{[black]}}{2CuO} + \underset{\text{Sulphur dioxide}}{2SO2} + O2}\]
