Calculate Concentrations in a Buffer (Example Problem)

The video tutorial explains how to calculate the number of moles of conjugate acid and base in a phosphate buffer solution using the Henderson-Hasselbalch equation. It covers the setup of a buffer problem, the calculation of moles for both conjugate acid and base, and the conversion of these moles into mass for practical lab preparation. The tutorial also discusses how to verify calculations by comparing pH and pKa values, ensuring the buffer is prepared correctly.
