Description

Eriochrome Black T is a chemical compound commonly used as an indicator in complexometric titrations, particularly for the determination of calcium and magnesium ions in water.

Chemical Formula: C20H12N3NaO7S
Appearance: It typically comes in a dark blue powder or a solid form.
Usage: It is used primarily in water testing and analytical chemistry for titrating metal ions, often in conjunction with EDTA (ethylenediaminetetraacetic acid).

General Applications of Eriochrome Black T:

Complexometric Titration: It helps in determining the concentration of metal ions by changing color at the endpoint of the titration. For example, it turns from blue to red as the metal ions are complexed with EDTA.
Water Quality Testing: It is used to measure hardness in water, which is caused by calcium and magnesium ions.

Handling and Storage:

Safety: Always handle with care and use appropriate personal protective equipment (PPE) like gloves and goggles. Follow safety data sheets for specific handling instructions.
Storage: Store in a cool, dry place, away from light and moisture, to maintain its stability.

If you have specific questions about its use or need information on how to prepare a solution or perform a titration with it, feel free to ask!
