Question

28. धातुओं की सक्रीयता श्रेणी से आप क्या समझाते है ? निम्नलिखित में से किसके साथ अभिक्रिया होगी?
(a) Zn(s) + CuSO (aq)→
(b) Fe(s)+ ZnSO,(aq)→
(c) Zn(s) + Feso,(aq) →​

Answer 1

i)  Zn(s) + CuSO (aq) → ZnSO(aq) + Cu(s)

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

ii) Fe(s) + ZnSO(aq) → NO REACTION

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

iii) Zn(s) + FeSO(aq) → ZnSO(aq) + Fe(s)

Reaction occurs because Zn is more reactive than iron.
