Answer:
The buffer adjusts the pH to ensure that the reaction goes to completion.
Explanation:
A complexometric titration uses the formation of a coloured complex to indicate the endpoint.
EDTA, often written as H4Y, is a common ligand in complexometric titrations.
It has four carboxyl groups and two amine groups that can act as electron pair donors (Lewis bases).
