Explanation / Answer

The potential of a silver:silver chloride reference electrode with respect to the standard hydrogen electrode depends on the electrolyte composition.

Lets consider, Ag/AgCl/Sat. KCl+0.197

E = E+(cathode) - E-(anode)

0.741 = E+(cathode) - 0.197
E+(cathode) = 0.938 V

when switch with calomel, Saturated calomel electrode (SCE) (E=+0.241 V saturated)

E = 0.938 - 0.241= 0.697V

given that E = 0.741 V
