Question

Why we use nh4oh and nh4cl buuffer in complexometric titration?

Answer 1

bcz to maintain a stable pH in which titration can proceed otherwise the titration may render useless if it is not used

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.
