1.If we wish to prepare a buffer with a pH of 9.39 from amixture of bicarbonate and carbonate, what ratio of carbonate:bicarbonate concentration should we use? (pKa2for carbonic acid is 10.25)
2.If you mix 125 mL of a buffer at pH 9.32 with 125 mL of purewater, what will be the pH of the resulting solution?
