Buffer pH Calculator

What is the use of the Buffer pH Calculator?

The Buffer pH Calculator is a tool that helps determine the pH of a buffer solution using the Henderson-Hasselbalch equation. This calculator is valuable for chemists, biologists, and students who need to prepare buffer solutions for experiments. It simplifies the process of pH calculation and ensures accuracy by factoring in the concentration of the acid and its conjugate base. With this calculator, you can save time and avoid manual calculation errors, especially when preparing solutions for pH-sensitive applications.

Formula: The formula used in this calculator is the Henderson-Hasselbalch equation:
pH = pKa + log10([A⁻]/[HA])

How to use the Buffer pH Calculator?

Enter the following values:

1. The pKa value of the acid (a constant for each acid).
2. The concentration of the conjugate base ([A⁻]).
3. The concentration of the weak acid ([HA]).

Click the "Calculate pH" button to get the result. The pH value will be displayed along with a step-by-step breakdown of the calculation. Use the "Clear" button to reset the fields.
