lon selective electrode (ISE) is an electrochemical device for the selective determination of the concentration/activity of an ion based on the principle of potentiometry. Typical examples include pH electrodes and the fluoride ISE. To use an ISE, the potential of the ISE is first measured with a range of solutions containing different concentrations of the analyte. Then, a calibration curve is constructed by plotting the potential versus log₁0[ion]. For an ideal Ca²+ ion selective electrode, which of the following slopes is the one that you would expect? (T = 25 °C) Select one: a. -30 mV/dec O b. O c. 30 mV/dec 59 mV/dec O d. -59 mV/dec
