pH of Acid Buffer Calculator

8 Views

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).

Step 1: Enter Buffer Parameters

Acid pKₐ:

Example: 4.76 (for acetic acid)

Conjugate Base Concentration, [A⁻] (mol/L):

Example: 0.1 M

Acid Concentration, [HA] (mol/L):

Example: 0.1 M
