A new method based on coulometric titration with potentiometric indication of the titration end point has been developed for the determination of the organic-acid content in wild-rose fruit, cholosas preparation, and wild-rose syrup. The relative error of the coulometric determination of organic acids does not exceed 2%.

Coulometric titration methods with potentiometric indication of the end-point have been developed for determining benzoic, salicylic, nicotinic, and ascorbic acids in various pharmaceutical dosage forms, liniments, and aqueous alcohol solutions. The relative standard deviation was within 0.01 -0.02.
