हिन्दीThe pH of an aqueous solution of a salt formed from a weak acid and a weak base is given by the relation:
Correct answer · Option 1
\( \text{pH} = 7 + \frac{1}{2}(\text{p}K_a - \text{p}K_b) \)
Explanation
For the salt of a weak acid and a weak base, the pH depends on \( \text{p}K_a \) and \( \text{p}K_b \) as \( \text{pH} = 7 + \frac{1}{2}(\text{p}K_a - \text{p}K_b) \).
