Answer:
zinc react with CuSo4 to give zinc sulphate and copper
aluminium react with HCl to give aluminium chloride and hydrogen
no reaction take place when silver place with CuSo4
- Explanation:
- Zn+CuSo4=ZnSo4+cu
- 2Al+6HCl=2AlCl3+3H2

Explanation:
(a) When zinc metal is added to copper sulphate solution, the colour of CuSO4 solution disappears and colourless zinc sulphate solution is formed. Solid brown copper is deposited as it displaces by Zn.
Zn + CuSO4---------> ZnSO4 + Cu
(b) Aluminium displaces hydrogen from HCl and hydrogen gas is evolved with soluble aluminium chloride.
2Al + 6HCl ----------> 2AlCl3 + 3H2
(c) Silver is a Nobel metal and does not exhibit any reaction with copper sulphate.
