Abstract The acid base determination of different substances 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 in lipide solvents may be inferred from their acid-base titration curves in such solvents. The properties of the phosphatides when titrated in non-aqueous media. When preparing a titrant solution, foam is always formed in the volumetric flask. This can be reduced addition of a few mL ethanol (max. 3-5 mL) just before finishing filling up to the graduation mark: first, a 1 L volumetric flas is filled up to e.g. The titration of weak organic bases (up to[equation] 10 11) with 0.005 N p-toluenesulphonic acid solution in chloroform can be carried out when Potentiometrie titrations in non-aqueous media yield valuable information about the basicity and acidity of compounds /1-2/.
