Abstract: The formal redox potential TiIII/TiIV was determined in the Na2СОз medium over the pH range from 7.35 to 9.52 by using EDTA. I t was found that the formate TiIII  complex in glycerine did not change its titre in air for 4 days. This solution was used as a volumetric reagent for the determination of [Fe(CN)6]3- and Cr2O72- ions in alkaline medium.
