Question

9. What happens when a piece of
(as zinc metal is added to coppeur
sulphate solution
(6) Aluminium metal is added to
coppeur sulphate solution.
Also write the balanced chemical
equation if the reaction occurs.​

Answer 1

Answer:

When zinc is added to cupper sulphate solution the colour of copper suplhate solution becomes colourless from blue . It is because Zinc displace Copper from its sulphate solution and forms Zinc sulphate

CuSO4 + Zn -----> ZnSO4 + Cu

When aluminium sulphate solution is added to Cupper sulphate solution then also cupper sulphate solution loses it color because aluminum displaces cupper from its solution

2Al + 3(CuSO4) -----> (Al)2(SO4)3 + 3Cu

Answer 2

In both reaction cupper will be displaced from it solution. Since aluminium and zinc are mor recative than cupper
