How does eriochrome black T acts as an indicator?

Anonymous

∙ 14y ago

Updated: 6/15/2024

Eriochrome black T acts as an indicator by forming complex ions with metal ions such as calcium, magnesium, and zinc. It changes color from blue to wine-red in the presence of these metal ions, allowing for visual detection of the endpoint in complexometric titrations.

Echnch Rome Blue Black T an indicator in EDTA titration?

Eriochrome Black T is a common indicator used in EDTA titrations, not Echnrome Blue Black T. Eriochrome Black T changes color from blue to magenta when it binds to the metal ions being titrated with EDTA, indicating the endpoint of the titration.

Why you add hydroxylamine hydrochloride in preparatin of Eriochrome Black T indicator?

Hydroxylamine hydrochloride is added in the preparation of Eriochrome Black T indicator to reduce the dye to its colored form. This reduction step is essential to activate the indicator dye and make it suitable for use in complexometric titrations, where it will form a colored complex with metal ions.

Name the indicator used in the edta method?

Erio Chrome Black-T, is usually used as indicator. It is commonly known as EBT. EBT can easily form weak complex ,which can be replaced easily by Sequencing agent Ethylene Diammine Tetra Acetic acid

What is the indicator used in EDTA method?

The indicator used in the EDTA method is typically Eriochrome Black T, or its chelates. This indicator changes color in the presence of metal ions, helping to determine the endpoint of the complexometric titration involving EDTA and metal ions.

Why murexide is prefer over eriochrome black t in estimation of nickel with edta?

Oh, dude, murexide is preferred over eriochrome black T in the estimation of nickel with EDTA because murexide forms a more stable complex with nickel ions, making it easier to detect and measure accurately. Plus, murexide has a more vibrant color change, so you can totally see when the reaction is happening. It's like choosing the cool kid in chemistry class - murexide just stands out more.
