Coulometric generation of acids and bases for acid–base titrations in non-aqueous solvents

A literature review of compounds which on electro-oxidation or reduction produce a strong acid or strong base in non-aqueous solvents is presented in this paper. The application of these compounds as anodic or cathodic depolarizers for coulometric titrations of acids, bases and salts as well as for the study of acid–base equilibria in non-aqueous solvents is also covered.
