Applications:
Eriochrome Black T is primarily used as an indicator in complexometric titrations to determine the concentration of metal ions. It forms a complex with metal ions, resulting in a color change. The dye exhibits a red-violet color in the presence of metal ions such as calcium (Ca2+), magnesium (Mg2+), and zinc (Zn2+). The color change helps in determining the endpoint of the titrationIt is important to note that Eriochrome Black T can interfere with certain metal ions, such as iron (Fe3+), by forming complexes even in the absence of the metal being analyzed. Therefore, it may not be suitable for titrations involving iron.
