What is the Henderson-Hasselbalch equation for the acidic buffer HA/A⁻?

Answered

For an acidic buffer composed of a weak acid (HA) and its conjugate base (A⁻), the Henderson-Hasselbalch equation is: pH = pKa + log10([A⁻]/[HA]). This form allows for the calculation of the pH of the buffer solution based on the known concentrations of the acid and its conjugate base.
