The Disodium EDTA (2H2O) ACS Analytical Grade by Dinâmica, available at LojaLab, is the disodium dihydrate salt of EDTA, widely used to prepare chelating solutions and in complexometric titrations. Compared with the acid form, it is more convenient to dissolve in water, but the concentration of a quantitative solution must still be calculated with the dihydrate molar mass and standardized when required by the method.
