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

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
