Question 1

In 0.100 M HC₂H₃O₂(aq), [H₃O⁺(aq)] = [C₂H₃O₂^-(aq)] = 1.3 × 10^-3 M. If a few drops of concentrated HCl(aq) are added to this solution, the C₂H₃O₂^-(aq) concentration is:
◦ < 1.3 × 10^-3 M
◦ > 1.3 × 10^-3 M
◦ = 1.3 × 10^-3 M
◦ 0.100 M

Question 2

In a solution prepared by mixing equal volumes of 0.20 M aqueous acetic acid and 0.20 M aqueous hydrobromic acid, the common ion is ________.
◦ Br^-
◦ C₂H₃O₂^2-
◦ H₂C₂H₃O₂
◦ H₂Br⁺
◦ H₃O⁺
