c) Buffer characteristics: 1) ..., 2) ...; Buffer components: 1) ..., 2) ...; pH = ...

d) Buffer characteristics: 1) ..., 2) ...; Buffer components: 1) ..., 2) ...; pH = ...

Answer 1

Buffer solutions have two main characteristics: They resist changes in pH and they maintain a relatively constant pH. The two components of a buffer solution are a weak acid and its conjugate base, or a weak base and its conjugate acid. The Henderson-Hasselbalch equation is used to determine the pH of a buffer solution.

Step-by-step explanation:

Buffer solutions have two main characteristics: They resist changes in pH and they maintain a relatively constant pH. The two components of a buffer solution are a weak acid and its conjugate base, or a weak base and its conjugate acid. The Henderson-Hasselbalch equation is used to determine the pH of a buffer solution. For example, to find the pH of an HF and F- buffer solution, we can calculate the ratio of F- to HF using the Henderson-Hasselbalch equation:

pH = pKa + log([A-]/[HA])

In this case, HF is the weak acid and F- is its conjugate base. By plugging in the values for pKa, [A-], and [HA], we can calculate the pH of the buffer solution.
