(a) Interpretation: Using the buffer index expression, the value of the buffer index for acetic acid buffer needs to be determined. Concept introduction: The buffer index is defined as the ratio of the increase in the concentration/amount of the strong acid or base added to the buffer with a change in the pH value. When a strong acid or base is added to the buffer solution, the change in the buffer index can be represented as follows: β = Δ c b Δ pH Here, Δ c b is the change in the concentration of the buffer and Δ pH is the change in the pH value.

Solution Summary: The author explains the value of the buffer index for acetic acid buffer.
Using the buffer index expression, the value of the buffer index for acetic acid buffer needs to be determined.
Concept introduction:
The buffer index is defined as the ratio of the increase in the concentration/amount of the strong acid or base added to the buffer with a change in the pH value. When a strong acid or base is added to the buffer solution, the change in the buffer index can be represented as follows:
β=ΔcbΔpH
Here, Δcb is the change in the concentration of the buffer and ΔpH is the change in the pH value.
Interpretation Introduction
(b)
Interpretation:
The pH of the buffer after the addition of strong acid needs to be determined.
Concept introduction:
The buffer index is defined as the ratio of the increase in the concentration/amount of the strong acid or base added to the buffer with a change in the pH value. When a strong acid or base is added to the buffer solution, the change in the buffer index can be represented as follows:
β=ΔcbΔpH
Here, Δcb is the change in the concentration of the buffer and ΔpH is the change in the pH value.
Interpretation Introduction
(c)
Interpretation:
A graph between buffer index and pH needs to be plotted indicating the minimum and maximum buffer indices.
Concept introduction:
The buffer index is defined as the ratio of the increase in the concentration/amount of the strong acid or base added to the buffer with a change in the pH value. When a strong acid or base is added to the buffer solution, the change in the buffer index can be represented as follows:
β=ΔcbΔpH
Here, Δcb is the change in the concentration of the buffer and ΔpH is the change in the pH value.
