In the analytic technique of potentiometry, a comparison is made between the voltage of one half-cell connected to another half-cell. It is customary that all half-cell potentials be compared to the potential generated by a standard electrode. This standard electrode is: a. A hydrogen electrode b. a calcium electrode c. a potassium electrode d. a copper electrode e. an iron electrode - A. a half-cell, also called an electrode, is composed of a single metallic conductor surrounded by a so...
