Product Description : Eriochrome Black T 

Eriochrome Black T is a complexometric indicator dye commonly used with EDTA titrants for determining water hardness and metal ion concentrations. Chemically, it is an azo dye with sulfonic acid groups, forming colored complexes with divalent metal ions, predominantly calcium (Ca²⁺) and magnesium (Mg²⁺).

When added to a solution containing metal ions, Eriochrome Black T forms a wine-red complex. Upon titration with EDTA, the dye releases the metal ion and shifts to a blue color at the endpoint, allowing precise visual determination.

Loba India manufactures this analytical-grade dye under strict ISO and laboratory standards to ensure high purity, batch-to-batch consistency, and chemical stability. Laboratories across Bangladesh—academic, industrial, and environmental—trust this reagent for accurate, reproducible, and reliable titration results.
