What will happen if you place zinc grannual in copper sulphate.(FULL EXPLANATION NEEDED WITH REACTION)

Answer»

Incorrect premise I’m afraid - Copper is below ZINC on the reactivity index and THUS cannot reduce zinc cations to the metal. It therefore will not dissolve at all, as no REACTION will occur.

Placing a zinc rod in a copper sulphate solution on the other HAND will SEE a reaction - the zinc will dissolve (as it reduces the Cu2+ ions to the elemental metal for the reason stated above), the blue colouration of the solution will fade and eventually disappear and copper metal will be deposited.
