Question

What is the standard reduction potential,E, for the half-reaction Zn2+(aq)+2e- -> Zn(s)?

Answer 1

Answer:

E = -0.76 V

Explanation:

The potential between the anode and the cathode is called standard reduction potential. It gives the tendency of the species to get reduced.

The given half reaction is :

$Zn^{2+}(aq)+2e^{-}\rightarrow Zn(s)$

Zn²⁺ is the reduced form of Zn.

It is a stronger reducng agent.

Its standard reduction potential (E) has a sandard value.

E = -0.76 V

Hence, the correct option is (c).
