Question

What is meant by reactivity series of metals? State which of the following

chemical reactions will take place giving suitable reasons for each.

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

(b) Fe (s) + ZnSO4 (aq) FeSO4 (aq) + Zn (s)

(c) Zn (s) + FeSO4(aq) ZnSO4 (aq) + Fe (s)​

Answer 1

Explanation:

State which of the following chemical reactions will take place or not, giving suitable reason for each:

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

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

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

i) 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.

Answer 2

Answer:

the series in which metals are arranged in decreasing order of its reactivity is known as reactivity series of metals.

a) 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.

b) Fe(s) + ZnSO4 (aq) → NO REACTION

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

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

Reaction occurs because Zn is more reactive than iron.

Hope this answer was heplful!!!
