Description
Eriochrome black T solution is a liquid formulation containing eriochrome black T, a synthetic dye commonly used as an indicator in analytical chemistry, particularly in complexometric titrations. The solution is prepared by dissolving eriochrome black T powder in a suitable solvent, often deionized water or alcohol. Eriochrome black T undergoes a distinct color change in the presence of metal ions, transitioning from red to blue or purple. This color change serves as an endpoint indicator in titration reactions, facilitating the determination of metal ion concentrations in solution. Eriochrome black T solution provides a convenient and standardized means of performing complexometric titrations.
