      (4)Buffer capacity does not represent the ability of a buffer to resist changes in pH. A: 正确 B: 错误

    • 2

      A buffer solution must contain a relatively large concentration of acid and a similar concentration of base.

      What is the pH of a buffer with the largest buffer capacity when the buffer is composed of NH3 (Kb = [img=80x24]1803a221c94490b.png[/img]) and HCl? A: 5 B: 6 C: 8 D: 9
