Short Communications


A method of conductometric titration for determination of methenamine is presented. An aqueous solution of silicotungstic acid is used as titrant. The acid and methenamine form an insoluble compound in which the molar ratio of the acid to methenamine is 1∶4. Conductometric curves were obtained, the shapes of which are suitable for accurate and reproducible determination of the end point of titration. The results show reasonable accuracy. Good reproducibility was achieved even when small quantities of methenamine had to be determined.
