An aqueous solution contains 0.29 M of benzoic acid (HA) and 0.16 M of sodium benzoate (A-). If the pH of this solution was meas
Inga [223]

Answer:

pKa = 4.89.

Explanation:

We can solve this problem by using the <em>Henderson-Hasselbach equation</em>, which states:

pH = pKa + log \frac{[A^-]}{[HA]}

In this case [A⁻] is the concentration of sodium benzoate and [HA] is the concentration of benzoic acid.

We <u>input the given data</u>:

4.63 = pKa + log \frac{0.16}{0.29}

And <u>solve for pKa</u>:

pKa = 4.89
