A pH electrode obeys the equation E= constant - 0.0592 pH. If the electrode potiential (E) is -0.105 V at 0.002500 M [H+], what is the electrode constant?

Using the electrode constant calculated abobe, determine the pH of a solution that gives the electrode potiential of -0.450V.

Sketch the calibration plot for the pH electrode.
Label the axes, electrode constant and the value of the slope on the calibration plot.
