What happens when a piece of

(a) zinc metal is added to copper sulphate solution?

(b) aluminium metal is added to dilute hydrochloric acid?

(c) silver metal is added to copper sulphate solution?

Also, write the balanced chemical equation if the reaction occurs

Answers (1)

(a) When Zinc is added to copper sulphate solution Zinc displaces copper to form Zinc sulphate.

Zn(s)+ CuSO_4(aq) \rightarrow ZnSO_4 (aq) + Cu(s)

(b) Aluminium metal reacts with dilute HCl to for Aluminum Chloride and Hydrogen gas is evolved in the reaction.

2Al (s)+ 6HCl (aq) \rightarrow 2AlCl_3(aq) + 3H_2

(c) When silver metal is added to Copper Sulphate solution there will not be any reaction as silver is non-reactive metal.
