About Eriochrome Black T Reagent Solution

Eriochrome Black T Reagent Solution is a high-quality analytical reagent in liquid form, primarily used in chemical analysis laboratory experiments and water hardness determination. This odorless solution, classified as a reagent solution, is not intended for consumption due to potential irritation risks upon exposure. With a purity specific to its concentration (e.g., 0.5% w/v), this ISO-standard solution contains the main material Eriochrome Black T, with a complex organic structure featuring azo groups, sulfonate, and aromatic rings. Suitable for complexometric titrations, especially for the accurate determination of water hardness, this dye indicator solution offers solubility in water and a pH level ranging approximately from 7 to 10 based on the buffer solution used. Ensure proper storage in a cool, dry place away from direct sunlight to maintain its efficacy.
