Question

What are the half-reactions for the following reference electrodes? Include physical states.

(b) The saturated calomel electrode. (ALL I NEED IS THIS EQUATION)

What are the half-reactions for the following reference electrodes? Include physical states. (a) The silver-silver chloride electrode. AgCls+e Ags+CI (aq) (b) The saturated calomel electrode. (c) What is the voltage of the cell: silver-silver chloride electrode l saturated calomel electrode given that the potential for the AglAgCl electrode in a saturated KCI solution is +0.197 V and the potential for a saturated calomel electrode is +0.241 V. Number

Explanation / Answer

calomel electronde reaction:

Hg2Cl2 (s) +2e- ------------------> 2Hg(s)   + 2 Cl- (sat)

explanation:

this reaction takes place at cathode : so reduction .

Ag / AgCl electrode can act as anode .

so cell potential Eocell = Eocathode - Eoanode

                                      = 0.241 - 0.197

                                   = 0.044 V
