Example: A quinhydrone electrode is placed in aqueous
solution of a weak acid and is connected to a calomel
electrode through a salt bridge. The cell is used in the
titration of the acid by NaOH. At 75% neutralisation, the
potential of the cell is 0.275V. The calomel electrode
potential is 0.2415V. The standard potential of the
quinhydrone electrode is 0.699V at 298K.
