Formula Used in “Buffer Capacity Calculator”
The Buffer Capacity Calculator utilizes the following standard formula to determine the buffer capacity of a solution:
Buffer Capacity (β) is expressed mathematically as:
β = frac{{dB}}{{d(pH)}}
Step-by-Step Breakdown of the Formula
This formula can be understood by breaking down the individual components:
- dB: This represents the change in the concentration of hydrogen ions (H+) or the change in the concentration of the buffer solution.
- d(pH): Indicates the change in the pH of the solution as a result of the additional H+ ions.
Calculating Buffer Capacity
The calculation process for determining buffer capacity can be structured in the following steps:
- Determine the initial concentration of the acid (HA) and its conjugate base (A–) in the buffer solution.
- Measure the initial pH of the buffer solution.
- Introduce a known amount of strong acid or strong base to the buffer and allow the system to reach equilibrium.
- Measure the final pH of the solution after the addition.
- Calculate the change in H+ concentration (dB) using the initial and final pH values.
- Divide the change in concentration (dB) by the change in pH (d(pH)) to find the buffer capacity (β).
Example Calculation
To illustrate the usage of the Buffer Capacity Calculator, let’s consider a practical example.
Input Data
We will examine a buffer solution of acetic acid (CH₃COOH) and sodium acetate (CH₃COONa). The following values will be measured:
| Parameter | Value |
|---|---|
| Initial Concentration of Acetic Acid (HA) | 0.1 M |
| Initial Concentration of Sodium Acetate (A–) | 0.1 M |
| Initial pH | 4.75 |
| Final pH after adding HCl | 4.50 |
Calculating Changes
Following the outlined steps:
- Calculate the initial H+ concentration from the initial pH:
H+ ≈ 10-4.75 = 1.78 x 10-5 M. - Calculate the final H+ concentration from the final pH:
H+ ≈ 10-4.50 = 3.16 x 10-5 M. - Determine dB:
dB = Final H+ – Initial H+ = (3.16 x 10-5 – 1.78 x 10-5) = 1.38 x 10-5 M. - Calculate the change in pH (d(pH)):
d(pH) = Final pH – Initial pH = 4.50 – 4.75 = -0.25. - Finally, calculate buffer capacity (β):
β = dB / d(pH) = (1.38 x 10-5) / (-0.25) = -5.52 x 10-5 M/pH.
This negative value for buffer capacity indicates a decrease in buffering ability due to the addition of strong acid. For more information on buffer systems, refer to Chemguide.
