Eriochrome Extra Pure

Original price was: $ 20.00.Current price is: $ 19.89.
Eriochrome Extra Pure—typically referring to Eriochrome Black T—is a complexometric indicator primarily used in EDTA titrations to detect metal ions, especially calcium (Ca²⁺) and magnesium (Mg²⁺) in water hardness analysis. In its extra pure grade, this dye ensures sharp, precise endpoint detection by minimizing impurities that could cause background coloration or interferences in spectrophotometric or volumetric determinations. It functions by forming a wine-red complex with metal ions, which turns blue when the metal is sequestered by EDTA. Suitable for high-precision analytical chemistry, it should be stored away from light and moisture to preserve stability.
