What happens when a piece of
a. Al metal is added to a dilute solution of HCl.
b. Zn metal is added to an aqueous solution of copper sulphate
c. Ag metal is added to an aqueous copper sulphate solution. Also write a balanced chemical equation if reaction occurs.

Explanation

a. Al metal displaces Hydrogen from HCl.
`2Al(s)+6HCl(aq)to2AlCl_(3)(aq)+3H_(2)(g)`
b. Zn metal displaces Cu from its solution.
`Zn(s)+CuSO_(4)(aq)toZnSO_(4)(aq)+Cu(s)`
c. No. reaction.
