Question

write chemical reaction for the following reaction and balance the reaction : when aluminium is immersed in the solution of copper sulphate thin layer of copper is formed on the solution of aluminum chloride​

Answer 1

Observation of student C are correct as Fe cannot displace Zn from its ZnSO4

solution.On the other hand Zn can displace Fe from FeSO4

solution to form ZnSO4

which is colourless and black coloured residue of Fe.The chemical equation for this reaction can be written as:

Zn+FeSO4 →ZnSO 4+Fe
