We are being asked to determine the reference electrodes and the voltage of the cell.
Recall that a reference electrode is an electrode with a stable and known potential.
What are the half-reaction for the following reference electrodes? Include physical states.
(a) The silver-silver chloride electrode
(b) The saturated calomel electrode.
(c) What is the voltage of the cell: silver-silver chloride electrode || saturated calomel electrode given that the potential for the Ag|AgCl electrode in a saturated KCl solution is +0.197 V and the potential for a saturated calomel electrode is +0.241 V?
