A bare silver wire electrode is dipped into a solution 0.05M in KNO3 and saturated in AgBr (Ksp = 5.0 x 10-13), as well as connected to the back of an mV/pH meter along with a saturated calomel reference electrode. Compute the potential of the silver electrode indicator. Compute the cell potential. KNO3 is simply present as supporting electrolyte.
