WHAT WILL HAPPEN IF:-
1) ZINC (in solid form) is added to a solution which is a mixture of IRON SULPHATE AND COPPER SULPHATE.
2)ALUMINUM(in solid form) is added to a solution which is a mixture of ZINC SULPHATE AND IRON SULPHATE.

Hello friend!
Here's ur answer!
1) Zinc is more reactive than copper. on adding zinc to CuSO4 solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution. This is indicated by colour change from blue to colourless.
Zn(s) + CuSO4(aq) ----> Cu(s) + ZnSO4 (aq).
When zinc is added to iron sulphate solution it displaces the iron from iron sulphate solution.
ZnS +FeSO4 ---->ZnSO4 +Fe
2) Aluminium displaces Zn from zinc sulphate solution, and Fe from ferrous sulphate solution.
