Suppose you want to prepare a buffer with a pH of 4.59 using formic acid. What ratio of [sodium formate]/[formic acid) do you ne

katrin [286]

Answer:

7.08

Explanation:

To solve this problem we'll use the Henderson-Hasselbach equation:

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

Where $\frac{[A^-]}{[HA]}$ is the ratio of [sodium formate]/[formic acid] and pka is equal to -log(Ka), meaning that:

pka = -log (1.8x10⁻⁴) = 3.74

We input the data:

4.59 = 3.74 + log $\frac{[A^-]}{[HA]}$

And solve for $\frac{[A^-]}{[HA]}$ :

0.85 = log $\frac{[A^-]}{[HA]}$

$10^{(0.85)}$ = $\frac{[A^-]}{[HA]}$

$\frac{[A^-]}{[HA]}$ = 7.08
