On adding zinc granules to freshly prepared ferrous sulphate solution, what is it observed?

Answer»

SOLUTION : It is OBSERVED that the solution TURNS from green to colourless and a black coating is formed. This is because zinc being more REACTIVE than iron displaced it from `FeSO_(4)` and forms colourless solution of `ZnSO_(4)` along with a black coating of FE.
`FeSO_(4)+Zntounderset(("Colourless"))+underset(("Black"))(Fe)`
