Convert the following voltages. Assume the silver-silver chloride and calomel reference electrodes are saturated with KCl, giving cell potentials of 0.197 V and 0.241, respectively.
(a) If an electrode has a potential of 0.397 V with respect to a standard hydrogen electrode (S.H.E.), what is the potential with respect to a silver-silver chloride electrode?
(b) If an electrode has a potential of -0.119 V with respect to a silver-silver chloride electrode, what is the potential with respect to a S.H.E.?
