Answer 1

In a buffer solution containing acetic acid and sodium acetate, the concentration of acetic acid will decrease if a small volume of HCl is added.

Step-by-step explanation:

In a buffer solution containing acetic acid (CH3COOH) and sodium acetate (CH3COONa), the concentration of acetic acid will decrease if a small volume of HCl is added.

When HCl is added, it reacts with the acetate ion (CH3COO-) from sodium acetate to form more acetic acid molecules. This reaction reduces the concentration of the acetate ion, while increasing the concentration of acetic acid. As a result, the overall concentration of acetic acid decreases.
