Question 1

What is the hydronium ion concentration of a 0.100 M acetic acid solution with a Ka = 1.8 × 10-5? The equation for the dissociation of acetic acid is:

CH3CO2H(aq) + H2O(l) ⇌ H3O+(aq) + CH3CO2-(aq).


◦ 4.2 × 10-2 M
◦ 1.3 × 10-2 M
◦ 4.2 × 10-3 M
◦ 1.3 × 10-3 M

Question 2

What is the hydronium ion concentration of a 0.100 M hypochlorous acid solution with Ka = 3.5 × 10-8? The equation for the dissociation of hypochlorous acid is:

HOCl(aq) + H2O(l) ⇌ H3O+(aq) + OCl-(aq).


◦ 5.9 × 10-5
◦ 1.9 × 10-4
◦ 1.9 × 10-5
◦ 5.9 × 10-4
