The method for determining the oxidation of organic substances is based on the absorption of carbon dioxide, produced by their combustion, in aqueous solution of barium hydroxide. Formation of an insoluble precipitate of barium carbonate changes the electrical conductivity of the solution, and the effect is utilized for continuous recording of the degree of conversion of the organic substances.
