Best Answer

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?

Murexide forms a more stable and colored complex with nickel compared to eriochrome black T, making it more suitable for accurate and sensitive estimation of nickel using EDTA titration. Eriochrome black T may not give as clear and distinct color changes, leading to less accurate results.

Why you use eriochrome black T indicator in EDTA titration?

Eriochrome black T is used as an indicator in EDTA titrations because it forms a stable complex with the metal ions being titrated. It changes color at the endpoint of the titration, which helps in detecting when all the metal ions have been chelated by the EDTA. This color change signifies the completion of the reaction and allows for accurate determination of the metal ion concentration.
