Question 1

The pH of a 0.23 M solution of a weak monoprotic acid, HA, is 2.92. Calculate the Ka for this acid.

◦ 0.23
◦ 1.2 × 10–3

◦ 5.3 × 10–3

◦ 6.3 × 10–6

◦ 4.0 × 10–11


Question 2

The pH of a 0.265 M solution of an aqueous weak acid (HA) is 3.20. The Ka for the weak acid is:

◦ 2.4 × 10–3.
◦ 4.0 × 10–7.
◦ 1.5 × 10–6.
◦ 3.2.
◦ None of these are correct.

An identified risk factor for osteoporosis is the intake of excessive amounts of vitamin A. Dietary intake of approximately double the recommended daily amount of vitamin A, by women, has been shown to reduce bone mineral density and increase the chances for hip fractures compared with women who consumed the recommended daily amount (or less) of vitamin A.

Women are two-thirds more likely than men to develop irritable bowel syndrome. This may be attributable to hormonal changes related to their menstrual cycles.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
