Description
Summary:The results of qualitative analysis of organic acids in multivitamin mixtures No. 1 and No. 2 are presented. The contents of malic, citric, and ascorbic acids were established in the mixtures by thin layer chromatography. The quantitative analysis of the sum of organic acids and ascorbic acid was carried out using the developed potentiometric titration procedure, and the results were compared with the data of indicator titration and coulometry. The advantage of using potentiometry for a more exact establishment of the final titration point was shown.
