✦ Synopsis

This paper deals with the study of the effect of acetic acid and sodium bicarbonate on the electrochemical reduction of phenylglyoxylic acid on a mercury electrode, as well as with the calculation of the rate constants of protonation by both proton donors with respect to that of H+ ion. Reaction orders for potentials corresponding to the foot of the wave (i/i, < 0.05) have also been determined.
