Chemistry - Electrochemistry Question with Solution | TestHub

If the opposing potential becomes slightly larger than that of the cell, the direction of current flow is reversed, and so is the cell reaction. Now zine ions are converted to zine at one electrode and $\mathrm{Cu}$ is converted into copper ion and the overall cell reaction becomes $${\mathrm{Zn}}^{2+}+\mathrm{Cu}\to \mathrm{Zn}+{\mathrm{Cu}}^{2+}$$
