Acid–Base Titrations in Nonaqueous Solvents and Solvent Mixtures
Lajos Barcza and Ágnes Buvári-Barcza
Institute of Inorganic and Analytical Chemistry, L. Eötvös University, Budapest 1518 Hungary

July 2003
Vol. 80 No. 7
p. 822
Abstract
The acid–base determination of different substances by nonaqueous titrations is highly preferred in pharmaceutical analyses since the method is quantitative, exact, and reproducible. The modern interpretation of the reactions in nonaqueous solvents started in the last century, but several inconsistencies and unsolved problems can be found in the literature. The acid–base theories of Brønsted–Lowry and Lewis as well as the so-called solvent theory are outlined first, then the promoting (and leveling) and the differentiating effects are discussed on the basis of the hydrogen-bond concept. Emphasis is put on the properties of formic acid and acetic anhydride since their importance is increasing.
