Description

By oxidation of solution of phosphoric acid and potassium permanganate in hot condition, sulfonic acid sodium salt and sulfonamide are changed to SO4-- that precipitates as BaSO4, then sulfonic acid sodium salt and sulfonamide are determined by weighing of BaSO4.<br>At 180-200°C sulfonic acid sodium salt and sulfonamide are decomposed, and the end point of the decomposition is indicated by the change of the phase of solution's by which the quantity of sulfo-compounds in a bright nickel plating bath can easily and accurately be determined.
