Titrations in nonaqueous solvents

“…Extensive reviews covering the chemical and physical properties of SO2 (44) and acyl halides (230) as aprotic solvents have appeared, as well as a review on acid-base equilibria in amphiprotic solvents, calculation of titration curves, scales of solvent acidity, and selection of optimum conditions for acid-base potentiometric titrations (47). A classification of solvents according to exchange processes has been presented (314).…”

Ion selective electrodes, potentiometry, and potentiometric titrations

“…Bykova and Petrov (182) review the entire field of nonaqueous acid-base equilibria and titrimetry, including scales of solvent acidity, selection of solvents and shapes of titration curves. Theoretical potentiometric titration curves for acids and bases in nonaqueous solvents are given by Kreshkov et al (605,606).…”
