Although the hydrogen electrode may be conceptually the simplest electrode and is the basis for the choice of reference potential in electrochemical systems, it is cumbersome to use. Therefore, several substitutes for it have been devised. One of these alternatives is the quinhydrone electrode (quinhydrone, Q ⋅ QH2, is a complex of quinone, C6H4O2 = Q, and hydroquinone, C6H4O2H2 = QH2), where the concentrations of Q ⋅ QH2 and QH2 are equal to each other. The electrode half-reaction is Q(aq) + 2 H+(aq) + 2 e− → QH2(aq), E⦵ = +0.6994 V. If the cell Hg(s)|Hg2Cl2(s)|HCl(aq)|Q ⋅ QH2|Au(s) is prepared, and the measured cell potential is +0.190 V, what is the pH of the HCl solution?
When the difference in pH across the membrane of a glass electrode at 25C is 4.63 pH units, how much voltage is generated by the pH gradient? Assume that the constant in Equation 15-6 is 1.00.
