Consider a reaction mixture containing 100.0 mL of 0.100 M borate buffer at pH 5 pKa 5 9.24. At pH 5 pKa, we know that [H3BO3] 5 [H2BO2 3 ] 5 0.050 0 M. Suppose that a chemical reaction whose pH we wish to control will be generating acid. To avoid changing the pH very much we do not want to generate more acid than would use up half of the [H2BO2 3 ]. How many moles of acid could be generated without using up more than half of the [H2BO2 3 ]? What would be the pH?
