Abstract: The formal redox potential Ti^III/Ti^IV was determined in the Na₂СО_з medium over the pH range from 7.35 to 9.52 by using EDTA. I t was found that the formate Ti^III  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 Cr₂O₇^2- ions in alkaline medium.
