Chapter 25, Problem 25.10QAP
Quinone undergoes a reversible reduction at a voltammetric working electrode. The reaction is
(a) Assume that the diffusion coefficients for quinone and hydroquinone are approximately the same and calculate the approximate half-wave Potential (versus SCE) for the reduction of hydroquinone at an RDE from a solution buffered to a pH of 8.0.
(b) Repeat the calculation in (a) for a solution buffered to a pH of 5.0.
