Answer:

There is not really a question here.......

Explanation:

And so we are forced to guess......

Typically, when we perform a complexometric titration we use #EDTA#, #"ethylene diaminetetra-acetic acid...."#

#""_2{HO_2CH_2}NCH_2CH_2N{CH_2CO_2H}_2#

Now this is a sexadentate chelating ligand, that is widely used in complexometric titration. Typically, when we perform these titrations, the solution is buffered to fairly high #pH#, and the ligand is delivered as its calcium salt......which #pH# gives a better chelating ability inasmuch as there are MORE carboxylate donors.

Anyway, you might have to re-specify your question, if this is inadequate.
