Question

For this equilibrium for acetic acid and acetate in water, HAc (aq) + H2O (l) ===== Ac- (aq) + H2O (l) Which species is the acid? Which species is the base? If we mix 50 mL of 0.1 M HAc and 50 mL of 0.05 M NaAc to prepare a buffer, what will be the concentrations of acid and base in the resulting 100 mL solution? If pKa for acetic acid is 4.74, then what is the pH of the prepared buffer?

Step 1

In the given reaction, HAc (aq) is the acid because it donates a proton (H+) to water, and Ac- (aq) is the base because it accepts the proton from water. Show more…
