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