Significant evolution or deposition occurs in electrolysis only if the overpotential exceeds about 0.6 V. To illustrate this criterion calculate the effect that increasing the overpotential from 0.40 V to 0.60 V has on the current density in the electrolysis of 1.0 m NaOH(aq), which is 1.0 mA cm−2 at 0.4 V and 25 °C. Take α = 0.5. Hint: Assume that the current is entirely anodic.
