Buffer Solution:
A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added. It consists of a weak acid and its conjugate base, or a weak base and its conjugate acid. Buffers are important in many biological and chemical processes, as they help maintain a stable pH.
Analysis of Options:
Let's analyze each given option to determine if it is a buffer solution.
Option a:
- 500 mL of 0.1 M CH3COOH (acetic acid)
- 500 mL of 0.1 M NaOH (sodium hydroxide)
This option does not form a buffer solution because it only contains acetic acid and sodium hydroxide, which are not a conjugate acid-base pair.
Option b:
- 500 mL of 0.2 M CH3COOH (acetic acid)
- 500 mL of 0.1 M NaOH (sodium hydroxide)
This option forms a buffer solution because it contains acetic acid and sodium hydroxide. Acetic acid is a weak acid, and sodium hydroxide is a strong base. When combined, they form a buffer solution consisting of acetic acid (weak acid) and the conjugate base of acetic acid (acetate ion).
Option c:
- 500 mL of 0.1 M CH3COOH (acetic acid)
- 500 mL of 0.2 M NaOH (sodium hydroxide)
This option does not form a buffer solution because it only contains acetic acid and sodium hydroxide, which are not a conjugate acid-base pair.
Option d:
- 500 mL of 0.1 M CH3COOH (acetic acid)
- 500 mL of 0.1 M HCl (hydrochloric acid)
This option does not form a buffer solution because it contains hydrochloric acid, which is a strong acid. A buffer solution requires a weak acid and its conjugate base or a weak base and its conjugate acid.
Conclusion:
Based on the analysis, option b is the only one that forms a buffer solution because it contains acetic acid and sodium hydroxide, which are a conjugate acid-base pair.
