Calculate the pH of a solution that is 0.40 M sodium acetate and 0.20 M acetic acid.

Question:

Calculate the pH of a solution that is 0.40 M sodium acetate and 0.20 M acetic acid.
K_a for acetic acid is 1.8 × 10^-5.
Strategy

The solution contains a weak acid and its conjugate base, so it is a buffer. Use the Henderson–Hasselbalch equation to solve for the pH of a buffer system. The analytical concentrations of the acid, base, and the value of K_a are given.
