EDTA is insoluble in water at low pH because H4Y is predominant in that pH (less than 2). With increasing the pH, each hydrogen ion in the carboxyl groups of EDTA will start to dissociate. Above pH 10, Y4- is predominant. As we need Y4- to react with the metal ions present in the titration solution, we use pH 10 buffer such as ammonium chloride.

May 26, 2022 · PH 10 buffer is used in EDTA titration because in EDTA Y4- is predominant and we want Y4- to react with the metal ions that are present in the titration solution. NOTE: The HCl will react with the conjugate base in the buffer (HPO 4 2−). Above pH 10, Y4- is predominant. hydrochloric acid on the pH of a buffer solution.
