3) Name the errors of glass electrodes in potentiometric measurements (please write correctly and concisely).
Consider the following statements as they apply to electrodes used in potentiometry. Decide if each is true or false. v Potentiometry is a technique in which only a very low current flows through the working electrode. A selectivity ratio of zero means that there is no interference from a particular ion. True True False v A saturated calomel electrode (SCE) is a common reference electrode that contains mercurous chloride, liquid mercury, and a saturated solution of KCI. False v A Ag/AgCl reference electrode can be used at temperatures higher than 60 °C whereas calomel electrodes cannot. False v A "combination" ion selective electrode (ISE) is a special electrode that measures more than one metal at a time. See Chapter 23 in your textbook. Submit Answer Incorrect.
