Question

What are the indicators used in complexometric titration?

Answer 1

Complexometric titration (sometimes chelatometry) is a form of volumetric analysisin which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution. An indicatorcapable of producing an unambiguous color change is usually used to detect the end-point of the titration.

Answer 2

Answer:

EDTA

Direct Titration- It is the most convenient and simple method of complexometric titration using EDTA. It is similar to acid-base titration technique. In this titration standard EDTA solution is added to given sample containing metals using burette till the end point is achieved.
