A buffer solution is prepared by mixing \[10\text{ }mL\] of \[1.0\text{ }M\] \[C{{H}_{3}}COOH\] and \[20\text{ }mL\] of \[0.5\text{ }M\]\[C{{H}_{3}}COONa\] and then diluted to \[100\text{ }mL\] with distilled water. If \[p{{K}_{a}}\] of \[C{{H}_{3}}COOH\] is \[4.76,\] what is the pH of the buffer solution?

Answer:

4.76
