Question

(i) Fe(s) + ZnSO4
(aq) ¾® FeSO4 (aq) + Zn(s)
(ii) Mg(s) + ZnSO4
(aq) ¾® MgSO4
(aq) + Zn(s)

Which amongst the above reaction will not proceed and why?​

Answer 1

Answer:

Zn(s) + CuSO4 (aq) → ZnSO4(aq) + Cu(s)

Reaction will take place as Zn is more reactive than copper. It displaces Cu from its solution.

ii) Fe(s) + ZnSO4 (aq) → NO REACTION

Reaction does not occur as iron is less reactive than Zn.

iii) Zn(s) + FeSO4(aq) → ZnSO4(aq) + Fe(s)

Reaction occurs because Zn is more reactive than iron.
