The selectivity coefficient, Kg-je, for a K* ion-selective electrode is 0.00348. When the electrode is placed into a 3.69 x 10- M K* solution at pH 6.77, the potential is --0.150 V vs. SCE. If the pH of the solution is lowered to 1.34 and the ionic strength is kept constant, what is the potential of the electrode? Assume = 1 for the electrode. E = V vs. SCE
