Assertion : Coppe

Answer :

(iv) Both assertion and reason are false.

Cu2+ + 2e- Cu(S) E° = 0.34V

Zn2+ + 2e- Zn(S) E° = -0.76V

Overall reaction,

Cu2+ + Zn(S) Cu(S) + Zn2+ ; E° = 0.34V – (-0.76V) = + 1.1V

Copper (Cu2+) sulphate can’t be stored in zinc vessel as Zinc is more reactive than Copper. Clearly, one can say that Zinc is a stronger reducing agent than Copper. Thus, Zinc donate electrons to Cu2+ and the above radox reaction occurs.
