Application of an indicating system of bismuth electrodes for the determination of organic bases and acids in nonaqueous solutions

Abstract

Tertiary amines and salts of organic acids have been titrated by means of perchloric acid applying a biamperometric indicating system consisting of a polarised or unpolarised pair of bismuth electrodes. Also, mono- and polycarboxylic acids, alone and in mixtures, have been determined with a strong base using the same end-point detection technique. The results obtained are in good agreement with those of potentiometry or catalytic thermometry. © 1971 Springer-Verlag.
