In EDTA titration, Eriochrome Black T (EBT) serves as an indicator by changing color to indicate the endpoint of the titration. EBT forms a complex with the metal ions present in the solution, and this complex has a different color compared to the free EBT. The color change signals the completion of the chelation reaction between EDTA and the metal ions being titrated.

Which indicators are used for cobalt with EDTA titration?
For titrating cobalt with EDTA, the indicator commonly used is eriochrome black T (EBT). EBT changes color from wine red to blue when the endpoint is reached during the titration process, making it suitable for detecting the formation of the Co(II)-EBT complex.
What is EDTA titration of Water?
It one of the titrations method to determine the permanent and temporary hardness of water. Procedure; step 1: standardise the edta solution step 2: titrate against the hard water mixed with ebt until the colour changes from wine red to blue. Then we can caluclate the normality using the formula (n1) *(v1)=(n2)*(v2). Posted by Krishna kanth yenumula.
What is the structure of ebt indicator?
EBT (Electronic Benefit Transfer) indicators typically consist of magnetic stripes or smart chips embedded in benefit cards. These indicators store data such as cardholder information, account balances, and transaction records, allowing users to access and manage their benefits electronically. The structure may vary depending on the specific EBT system or program in use.
Why EBT indicator do not form complex with Mg ions?
EBT (Eriochrome Black T) is a metal indicator that forms stable complexes with certain metal ions like Ca^2+ and Mg^2+. In the case of Mg^2+ ions, the complex formed with EBT is not very stable due to the weaker coordinating ability of Mg^2+ compared to other metal ions like Ca^2+. This results in poor formation of complexes between EBT and Mg^2+ ions.
What is the common and IUPAC name of EBT indicator?
common name: Eriochrome black T IUPAC name: Sodium 4-(1-hydroxy-2-naphthylazo)-3-hydroxy-7-nitronapthalene-1-sulphonate

Why is EBT indicator used for EDTA complexometric titration in determining water hardness?
The Eriochrome Black T (EBT) indicator changes color when it forms a complex with calcium and magnesium ions, which are responsible for water hardness. This color change signals the endpoint of the titration when all the calcium and magnesium ions are complexed with EDTA. Therefore, EBT is used to detect the endpoint of the titration and determine the water hardness.
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
Why you use pH 10 buffer in EDTA titrtion?
A pH 10 buffer is used in EDTA titration because it ensures that the metal ions being titrated remain in their complexed form with EDTA, which has higher stability at alkaline pH. This helps in achieving accurate and precise results in the titration process.

How does the behavior of indicator EBT changes with pH?
The color of the EBT indicator changes from red to yellow as pH increases. EBT transitions from its acidic form to its basic form as pH rises above its pKa of approximately 7.0, causing the color change.
What is the structure of ebt indicator?
EBT (Electronic Benefit Transfer) indicators typically consist of magnetic stripes or smart chips embedded in benefit cards. These indicators store data such as cardholder information, account balances, and transaction records, allowing users to access and manage their benefits electronically. The structure may vary depending on the specific EBT system or program in use.
What is the structure of edta and ebt?
The structure of EDTA (ethylenediaminetetraacetic acid) consists of four carboxylic acid groups and two amine groups attached to a central metal ion binding site. EBT (Eriochrome Black T) is a tridentate ligand with three oxygen atoms in the ligand structure that can form complexes with metal ions.
Why EBT indicator do not form complex with Mg ions?
EBT (Eriochrome Black T) is a metal indicator that forms stable complexes with certain metal ions like Ca^2+ and Mg^2+. In the case of Mg^2+ ions, the complex formed with EBT is not very stable due to the weaker coordinating ability of Mg^2+ compared to other metal ions like Ca^2+. This results in poor formation of complexes between EBT and Mg^2+ ions.
What is the common and IUPAC name of EBT indicator?
