Question

What happens when a piece of a) zinc metal is added to copper sulphate solution?b) aluminium 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

Answer 1

Explanation:

a).when we add zinc metal to copper sulphate solution then we get the solution of zinc sulphate .and we get a thin layer of copper on zinc metal.

Zn+CuSO4-ZnSO4+Cu

b).

when aluminium is added to dilute hydrochloric acid,then we get the solution of aluminium chloraide and hydrogen gas will come out from the solutuon.

2Al+6HCl=2AlCl3+3H2

c).when silver is added to copper sulphate solution we get solutioñ of silver sulphate and a layer of copper is found on silver metal.

2Ag+CuSO4=Ag2SO4+Cu
