Consider the following statements as they apply to electrodes used in potentiometry. Decide if each is true or false. True - Potentiometry is a technique in which only a very low current flows through the working electrode. True - A selectivity ratio of zero means that there is no interference from a particular ion. False A saturated calomel electrode (SCE) is a common reference electrode that contains mercurous chloride, liquid mercury, and a saturated solution of KCI. False A Ag/AgCl reference electrode can be used at temperatures higher than 60 °C whereas calomel electrodes cannot. False A "combination" ion selective electrode (ISE) is a special electrode that measures more than one metal at a time.

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
