A glass pH electrode produced a response according to Equation 15-6. (a) Suppose 3=1.00 and the outside of the electrode is immersed in a pH 1.00 solution. If a voltage of -50.21 mV is produced at 25C, then what is the value of the constant in the equation? mV (b) Assume the constant is the same as in (a) but the solution pH on the outside of this glass electrode is 4.78 at 25C. What is the voltage output of the electrode? mV (c) Assuming the glass electrode has the same constant value as you found in (a) but the solution in (b) produced an electrode voltage of -251 mV at 25C, what is the value of 3?
