The pH of the...

Question

The $p H$ of the solution containing $50 mL$ each of $0.10$ sodium acetate and $0.01 M$ acetic acid is
[Given $p K_{a}$ of $C H_{3} C O O H = 4.57$ ]

Open in App

Solution

Given solution is acidic buffer solution.
$p H = p K a + log \frac{[Salt]}{[Weak acid]}$
$= 4.57 + log \frac{0.1}{0.01} = 5.57$
