pH of Salt of Weak Acid and Weak Base Calculator

Calculate the pH of a solution formed by the salt of a weak acid and a weak base using:
\[ \text{pH} = 7 + \frac{1}{2}\left(pK_a - pK_b\right) \]

* Enter the weak acid’s pKₐ and the weak base’s pK_b.

Step 1: Enter Parameters

Weak Acid pKₐ:

Example: 4.76 (for acetic acid)

Weak Base pK_b:

Example: 4.75 (for ammonia)
