to study reactions of metals zn fe cu al with all solutions salts znso4 feso4 cuso4 diagram

Answer 1

Hello dear,
It's a long question so I'll just mention important reactions.

● Relative Reactivity of metals -
- Zinc replaces copper as well as iron from their sulphates-
Zn + CuSO4 ---> ZnSO4 + Cu
Zn + FeSO4 ---> ZnSO4 + Fe

- Iron replaces copper from copper sulfate,
Fe + CuSO4 ---> FeSO4 + Cu

- Copper is least reactive so won't replace any metal.

- Aluminium is most reactive, thus replaces zinc, iron and copper from their respective sulfate s,
2Al + 3ZnSO4 ---> Al2(SO4)3 + 3Zn
2Al + 3CuSO4 ---> Al2(SO4)3 + 3Cu
2Al + 3FeSO4 ---> Al2(SO4)3 + 3Fe

Hope this is useful..
