How does ebt function as an indicator in the edta titration?
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.
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.
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 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
How does an acid affect an indicator?
Acids typically change the color of an indicator by donating a hydrogen ion (H+) to the indicator molecule, altering its structure and causing a shift in color. The specific color change depends on the pH range of the indicator and its chemical properties.
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.

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

This results in poor formation of complexes between EBT and Mg^2+ ions.
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.
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 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 is the indicator EBT shows wine red at the beginning and blue at the end?
The EBT (Electrolyte Balance Test) indicator typically shows wine red at the beginning due to the presence of certain acidic compounds in the solution, which create a red color. As the test progresses and the pH level increases, the indicator undergoes a color change to blue, signaling a shift to a more alkaline environment. This transition reflects the chemical reactions occurring during the test, indicating the balance of electrolytes in the sample.
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
What is the structure of pan indicator?
