State one appropriate observation when Concentrated sulphuric acid is added dropwise to a crystal of hydrated copper sulphate

Open in App

Solution

In this reaction concentrated sulphuric acid acts as a strong dehydrating agent.
It dehydrates the salt and the colour changes from blue to colourless.
The required chemical reaction is : ${CuSO}_{4} . 5 H_{2} O \to H_{2} {SO}_{4} (conc .) + {CuSO}_{4} + 5 H_{2} O$
