Henderson-Hasselbalch Calculator

What is Henderson-Hasselbalch Calculator?

The Henderson-Hasselbalch Calculator helps in calculating the pH of a solution based on the concentrations of an acid and its conjugate base. The formula used in this calculator is derived from the Henderson-Hasselbalch equation, which relates the pH of a buffer solution to the pKa and the concentrations of the acid and its conjugate base.

How to Use Henderson-Hasselbalch Calculator Website?

To use this calculator, simply input the concentration of the acid (HA), the concentration of the conjugate base (A-), and the pKa value of the acid. Click the 'Calculate pH' button, and the calculator will display the pH of the solution based on the provided values.

What is the Formula of Henderson-Hasselbalch Calculator?

The formula used by the Henderson-Hasselbalch Calculator is:

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

Where:

• pH is the acidity of the solution.
• pKa is the acid dissociation constant.
• [A-] is the concentration of the conjugate base.
• [HA] is the concentration of the acid.

Advantages and Disadvantages of Henderson-Hasselbalch Calculator

Advantages:

• Quick and easy to use for calculating pH.
• Accurate results when the correct concentrations and pKa values are provided.
• Helps in understanding the relationship between acid, base, and pH in buffer solutions.

Disadvantages:

• Accuracy depends on the precision of input values.
• Only works for buffer solutions and may not be accurate for strong acids/bases.
