Webb9 apr. 2014 · Carrying out the reaction in a basic buffer solution removes the H+ as it is formed. This moves the position of equilibrium to the right and favours formation of the complex (Le Châtelier's Principle). Also, for EDTA, pKa4 = 10.26. Thus, if the solution is buffered to about pH 10.3, most of the EDTA will exist as Y4- ions.
