If an electrode has a potential of -1.004 V with respect to a saturated calomel electrode, what is the potential with respect to a silver-silver chloride electrode (with saturated KCl)? (Hint: It might be useful to compare the two reference electrode potentials and the cell potential on a potential coordinate.)
