Calculate Buffer Capacity





Formula

To calculate the Buffer Capacity (B):

\[ B = \frac{n}{pH2 - pH1} \]

What is Buffer Capacity?

A buffer capacity is defined as a solution’s ability to resist a change in acidity or pH. It measures how well a solution can maintain its pH when an acid or base is added.

Example Calculation

Let's assume the following values:

Using the formula:

\[ B = \frac{0.1}{4.5 - 4.0} = \frac{0.1}{0.5} = 0.2 \text{ moles/liter} \]

The Buffer Capacity is 0.2 moles/liter.
