WebThe iodimetric method for ascorbic acid determination is recommended for routine testing. Excellent reproducible equivalent points, in colored as well as colorless solutions, may be obtained by the use of a vacuum tube potentiometer (titrimeter). The polarized platinum‐platinum electrode system serves best in this titration.

WebIodometric methods can be used for the quantitative determination of strong oxidizing agents such as potassium dichromate, permanganate, hydrogen peroxide, cupric ion and oxygen. As has been mentioned above, the endpoint in a titration of iodine with thiosulfate is signaled by the color change of the starch indicator.
