30 mol of $0.1 M CH_{3} COOH$ (aq.) is mixed with 10 ml of 0.1 M NaOH (aq.) pH of resulting solution

Answer:

Solution:

Concepts: Limiting reagent, Henderson-Hasselbalch equation, buffer solution.

$p H = p K_{a} + lo g \frac{[ C H _{3} COON a ]}{[ C H _{3} COO H ]}$

$p H = 4.74 + lo g \frac{0.025}{0.05} = 4.44$
