pH of Acid Buffer Calculator
Calculate the pH of an acid buffer solution using the Henderson–Hasselbalch equation:
\[
\text{pH} = \text{p}K_a + \log\left(\frac{[\text{A}^-]}{[\text{HA}]}\right)
\]
* Enter the pKₐ of the acid, the concentration of the conjugate base [A⁻] (mol/L), and the concentration of the acid [HA] (mol/L).
