Question: Why is buffer solution used in complexometric titration?
Buffer solution is used in complexometric titration because it helps to maintain a consistent pH throughout the titration process. This helps ensure accuracy and reproducibility, as well as prevents the interfering precipitation of metal species during the reaction. The pH of the buffer solution should be similar to the pKa of the chelating agent and near the endpoint of the titration.
