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

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 :
[tex]Zn^{2+}(aq)+2e^{-}\rightarrow Zn(s)[/tex]
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).
