How to use the Henderson-Hasselbalch equation?

Understand the Problem

The question is asking for guidance on how to utilize the Henderson-Hasselbalch equation, which is typically used in chemistry and biology to calculate the pH of a buffer solution based on the concentrations of the acid and its conjugate base.

Answer

Use pH = pKa + log([A-]/[HA]) with the values for pKa, [A-], and [HA].

The final answer is to use the Henderson-Hasselbalch equation, pH = pKa + log([A-]/[HA]), and input the values for pKa, the concentration of the conjugate base [A-], and the concentration of the acid [HA] to calculate the pH of a buffer solution.

Answer for screen readers

The final answer is to use the Henderson-Hasselbalch equation, pH = pKa + log([A-]/[HA]), and input the values for pKa, the concentration of the conjugate base [A-], and the concentration of the acid [HA] to calculate the pH of a buffer solution.

More Information

The Henderson-Hasselbalch equation simplifies the process of determining the pH of buffer solutions, which is vital in many chemical and biological processes.

Tips

A common mistake is to swap the concentrations of the acid and its conjugate base in the equation, which will give an incorrect pH value.
