The Trisodium EDTA (3H2O) Analytical Grade by Dinâmica, available at LojaLab, is the trisodium trihydrate form of EDTA, with an intermediate neutralization level between the disodium and tetrasodium salts. It is used to prepare chelating solutions where solubility, alkalinity and availability of complexing groups must be balanced. Selection of this form must consider final pH rather than only the desired EDTA mass.
