Question

You have at your disposal an ample quantity of a solution of $1.439 \times 10^{-2}$ M HCl and 750.00 mL of a solution of $1.919 \times 10^{-3}$ M potassium acetate. How much of the HCl solution should be added to the potassium acetate solution to produce a buffer of pH 4.322? The $pK_a$ for acetic acid is 4.760. 173.95 mL HCl

Step 1

Step 1: We can use the Henderson-Hasselbalch equation to solve this problem: $pH = pK_a + log \frac{[A^-]}{[HA]}$ where $[A^-]$ is the concentration of the conjugate base (acetate) and $[HA]$ is the concentration of the weak acid (acetic acid). Show more…
