Suppose that you have a supply of each of the acids listed in Table 11.1 and each of the bases listed in Table 11.2, as well as 1.00 M HCl solution and 1.00 M NaOH solution. Describe how you would prepare 1.00 L of an effective buffer solution at each of the following pH values. Specify (i) which acid or base you would use (in each case, use 0.100 mol) and (ii) whether you would add HCl or NaOH, and how much. (a) pH = 2.50 (b) pH = 7.00 (c) pH = 11.75
