A cell composed of a platinum indicator electrode and a silver-silver chloride reference electrode in a solution containing both Fe2 and Fe3 has a cell voltage of 0.719 V. If the silver-silver chloride electrode is replaced with a saturated calomel electrode, what is the new cell voltage? The answer is not 0.2444 or 0.475 It also gives a hint of The [Fe2 ]/[Fe3 ] does not change when the reference electrode is changed.
