✦ Synopsis

We carried out a theoretical treatment of the reduction of o-keto acids, the limiting current of which typically reaches a maximum value at a given pH.

Provided the protonated form of an a-keto acid is strongly hydrated in solution and the protonation equilibria involved are substantially faster than those of hydration, which is usually the case with these compounds, one can derive approximate expressions of the overall representative equations, which considerably simplifies numerical fitting of experimental results.

The treatment developed in this work was applied to the first reduction wave of glyoxylic acid and the rate constants of the process were calculated.
