Henderson-Hasselbalch Equation Explained | pH & Buffer Example Problem

Learn how to use the Henderson-Hasselbalch equation to calculate the pH of a buffer solution. In this worked example, we use benzoic acid and sodium benzoate to walk through the calculation step by step, including: How the Henderson-Hasselbalch equation works How to calculate pKa from Ka How to identify the acid and conjugate base concentrations How to calculate the pH of a buffer solution What the result tells us about the buffer Useful tips for understanding pH and buffer capacity The Henderson-Hasselbalch equation is: pH = pKa + log([A⁻]/[HA]) This video is designed for students studying general chemistry, acid-base chemistry, buffers, equilibrium, or biochemistry, as well as anyone who wants a straightforward worked example.
