ABSTRACT
In purely aqueous solution, the half-wave potential E112 for the general reversible reaction shown in Scheme 5 is given by Eq. (83) (at T = 298 K).
_ pH=O ill E1e - E112 - 0.0591-pH ~ n
(83)
Thus for two reaction schemes commonly met in organic electrochemistry, m = n = 1 and m = n = 2, a plot of E 1;2 versus pH should yield a straight line with the slope 59 mV/pH. Numerous examples of the variation of E 112 with changing pH have been reported [243245].
