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

What is the method for making mordant black 2 indicator?
mordant black 2 is used as an indicator in comleometric titrations, usuall against Di Na EDTA Solution. the indicator is mixed with NaCl/ KI in appropriate quantity...
Why is buffer solution used in EDTA method?
Buffer maintains the pH of the solution through out the reaction. To maintain high alkaline medium ammonia buffer is added to EDTA in analysis of hard water. It is necessary to keep the pH at about 10 for two reasons: (a) all reactions between metal ions and EDTA are pH dependent, and for divalent ions, solutions must be kept basic (and buffered) for the reaction to go to completion; (b) the eriochrome black T indicator requires a pH of 8 to 10 for the desired color change.
Why is EBT indicator used for EDTA complexometric titration in determining water hardness?
ebt is used to get the end point of reaction that is in the end point it gives steel blue colour describing that the reaction completed now

What are different types of EDTA titration?
1. Direct Titration In direct titration, you simply add an indicator to the solution of the metal ion and titrate with EDTA. Before starting the titration,it is needed to check that the pH of the solution to obtain a good formation constant value and on the other hand indicator colour change as well. 2.Indiract titration EDTA can be used as titrant for anions. Anions can be precipitated with suitable metal ion. Filter and wash the ppt with proper solution. Then boil in excess EDTA to complex metal ion(ppt). Back titrate to determine how much metal ion you had. 3.Back Titration In a back titration an excess of EDTA is added to the metal ion solution, and the excess EDTA is titrated with a known concentration of a second metal ion. The second metal ion must form a weaker complex with EDTA than the analyte ion so the second metal does not displace the analyte ion from its complex with EDTA. 4.Displacement titration Here the analyte is treated with an excess of a second metal bound to EDTA. The analyte ion displaces the second metal from the EDTA complex, and then the second metal is titrated with EDTA.
What is disodium edta?
Used in solarcaine.
What is the name of the pH indicator used in microbiology?
lithmus
What is EDTA why it is used for treating hardness of water?
EDTA is ethylenediaminetetraacetic acid; the chemical formula is C10H16N2O8.EDTA can react with calcium and magnesium ions forming insoluble precipitates.
Is EDTA used for the desulfation of car batteries?
yes
What is equivalent weight of disodium EDTA?
EDTA (Na2H2EDTA.2H2O) is 374.24g/mol Be careful not to confuse pure EDTA with the required EDTA used in the lab. C10H12N2O8•4Na is the correct chemical formula for lab use and is the MW above.
