举一反三
- (4)Buffer capacity does not represent the ability of a buffer to resist changes in pH.
- The larger the value of β，the greater the capacity of the buffer to resist changes in pH.
- The more the total concentration of a buffer, the more its buffer capacity at 298K. A: 正确 B: 错误
- 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
- Regarding the determination of the effective buffer range of the buffer solution, which of the following is not the factor we should consider A: pH= pKa±1 B: The buffer ratio is between 0.1 and 10 C: Large buffer capacity D: High total concentration
