(3)Choose the factors that can not determine the capacity of a buffer from the following a. pH of the buffer b. Concentration of buffer-component reservoirsc. Buffer-component ratio d. Buffer range
A: a
B: b
C: c
D: d
A: a
B: b
C: c
D: d
举一反三
- 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
- The more the total concentration of a buffer, the more its buffer capacity at 298K.
- 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
- A buffer can only sustain its pH within its buffer capacity.
- （） is typically not referred to as a buffer type in critical chain project management． A: Resource buffer B: Free buffer C: Feed buffer D: Project buffer
