Suppose that the Ag | AgCl outer electrode in Figure 14-11 is filled with 0.1 M NaCl instead of saturated KCl. Suppose that the electrode is calibrated in a dilute buffer containing 0.1 M KCl at pH 6.54 at 25°C. The electrode is then dipped in a second buffer at the same pH and same temperature, but containing 3.5 M KCl. Use Table 14-2 to estimate how much the indicated pH will change.
