TheKaof the conjugate acid in a buffer solution is 1.0×10-6, it is theoretically inferred that the effective buffer range of the buffer solution is
A: 6~8
B: 7~9
C: 5~7
D: 5~6
A: 6~8
B: 7~9
C: 5~7
D: 5~6
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
- 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 solution whose hydroxide concentration is 10-8 M, the pH of the solution is A: 5 B: 6 C: 7 D: 8
- A buffer solution must contain a relatively large concentration of acid and a similar concentration of base.
- According to the definition of buffer solution, the option that cannot form a buffer is A: HCl B: NaH2PO4 C: NaAc D: NH4Cl-NH3
