Coulometric titration of acids in isopropanol-II Electrode reactions with lithium chloride and tetraethylammonium bromide as supporting electrolytes.
Cathodic reactions in methanol and isopropanol have been investigated in the presence of both lithium chloride and tetraethylammonium bromide as supporting electrolytes. A side-reaction in lithium chloride medium leads to the formation of insoluble lithium hydroxide but base is generated stoichiometrically in tetraethylammonium bromide by reduction of solvent, oxygen and traces of water. Tetraethylammonium bromide is recommended as supporting electrolyte for the coulometric titration of acids in isopropanol.
