Frequently Asked Questions
What is Alcoholic Eriochrome Black Solution used for?
Alcoholic Eriochrome Black Solution is used as a metallochromic indicator in EDTA titrations, mainly for calcium, magnesium, and water-hardness determinations.
What are the main characteristics of Alcoholic Eriochrome Black Solution?
Alcoholic Eriochrome Black Solution contains Eriochrome Black T in an alcoholic medium and is available in 1 L and 500 mL, providing the indicator in liquid form for volumetric addition.
What is the role of Alcoholic Eriochrome Black Solution at the endpoint of an EDTA titration?
Alcoholic Eriochrome Black Solution forms a colored complex with ions such as Ca2+ and Mg2+. As EDTA complexes these metals, the indicator color response changes, allowing the method endpoint to be recognized.
