Summary

The first part of this chapter reviews the terminology and conventions for working with redox reactions. These conventions include using standard reduction potentials and the Nernst equation, and the energetics of electrochemical cells. The chapter uses standard reduction potentials to predict if redox reactions will be spontaneous. The latter part of the chapter describes a variety of electroanalytical methods for making quantitative measurements. The two main variations are: potentiometry—measurement of a voltage under conditions of no current flow, and voltammetry—measurement of a current induced by an applied potential. Any analyte can be detected by potentiometry if a robust ion-selective membrane is available.
