Suppose to you want to prepare a buffer with a pH of 6.5 and you have a choice of using different components of two acids: Tartaric acid (C4H6O6) is a diprotic acid with pKa1 = 3.00 and pKa2 = 4.35 Maleic acid (C4H4O4) is a diprotic acid with pKa1 = 1.95 and pKa2 = 6.23 Which components should you use to make the most effective buffer with a pH of 6.5
