1. A solution of hydrochloric acid is titrated at 25 C with 0.1 mol-eq/l NaOH solution using a quinhydrone indicator electrode (E0HG = 0.699 V). Neglecting dilution, evaluate the potential of the indicator electrode at the end of the titration, when the system under study contains an excess of the working solution.
