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.
Webb11 nov. 2024 · pH = pK a + log 10 ( [A - ]/ [AH]) Where the square brackets are used to indicate the concentrations of the acid and its conjugate base. The equation may be rewritten as: K a / [H +] = [A - ]/ [AH] This shows that pKa and pH are equal when half of the acid has dissociated.
