Question

Wired Faculty App

What is the effect of an increase in the concentration of zinc ions on the electrode potential of zinc electrode for which E° equals – 0.76 V?

Solution

Answer:

According to Nernst equation, the electrode potential of zinc electrode will increase with the increase in the concentration of zinc ions.

E = E ° + \frac{2.303 RT}{nF} \log [{Zn}^{2 +}] .
