What is example of indicator in EDTA titration?
The indicator commonly used in EDTA titrations is Eriochrome Black T. It changes color from wine-red to blue when transitioning from calcium ions to magnesium ions, helping to detect the endpoint of the titration accurately.
What is another example of indicator that used in titration with EDTA?
Another example of an indicator used in a titration with EDTA is Eriochrome Black T. This indicator changes color from red to blue when it forms a complex with metal ions, allowing for the detection of the end point in the titration.
What is role of eriochrome black t in zn-edta titrations?
The indicator added to the sample is Eriochrome Black T. Initially, the indicator will form a complex with the cations. When complexed it is red in color. As the EDTA is added dropwise to the sample, it replaces the Erio T and forms more stable complexes with calcium and magnesium. When the indicator is released by the metal ions, it has a distinct blue color. Therefore, the endpoint of the titration is marked by the color change form red to blue
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.
How you can do EDTA titration reaction?
To perform an EDTA titration, first prepare a solution containing the analyte (the substance being measured) and a suitable indicator, such as Eriochrome Black T. Add a standardized solution of EDTA to the analyte solution until the endpoint is reached, indicated by a color change in the indicator. The volume of EDTA solution added can be used to calculate the concentration of the analyte based on the stoichiometry of the reaction.
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.

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.

The indicator added to the sample is Eriochrome Black T. Initially, the indicator will form a complex with the cations. When complexed it is red in color. As the EDTA is added dropwise to the sample, it replaces the Erio T and forms more stable complexes with calcium and magnesium. When the indicator is released by the metal ions, it has a distinct blue color. Therefore, the endpoint of the titration is marked by the color change form red to blue
Why pink colour of edta changes to blue at the end point in the edta titration of water using erochrome black-t indicator?
In an EDTA titration using Eriochrome Black T indicator, the pink color indicates the presence of free metal ions, such as calcium or magnesium, which form complexes with the indicator. As EDTA is added, it binds to these metal ions more strongly than the indicator does, causing the indicator to release the metal and change color. At the endpoint, when all the metal ions have reacted with EDTA, the indicator turns blue due to its transition to a form that is free of metal ions, indicating that the titration is complete.

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.
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
How do you standardize 0.02N EDTA solution?
To standardize a 0.02N EDTA solution, you can use a calcium or magnesium salt solution of known concentration. First, prepare a sample of the metal salt and titrate it with the EDTA solution, using a suitable indicator like Eriochrome Black T for calcium or magnesium. The endpoint is reached when the color changes, indicating that all metal ions have complexed with the EDTA. Calculate the exact normality of the EDTA based on the volume used in the titration and the initial concentration of the metal salt.
