The selectivity coefficient, Kg+Ht, for a K* ion-selective electrode is 0.00843. When the electrode is placed into a 3.84 x 10-5 M K* solution at pH 6.76, the potential is -0.157 V vs. SCE. If the pH of the solution is lowered to 1.24 and the ionic strength is kept constant, what is the potential of the electrode? Assume = 1 for the electrode. E = V vs. SCE
