Question 1

Due to a highway accident, 150 L of concentrated hydrochloric acid (12.0 M) is released into a lake containing 5.0 × 105 m3 of water.  If the pH of this lake was 7.0 prior to the accident, what is the pH of the lake following the accident?
◦ 5.44
◦ 8.56
◦ 8.44
◦ 5.56
◦ 2.44

Question 2

For H3PO4, Ka1 = 7.3 × 10–3, Ka2 = 6.2 × 10–6, and Ka3 = 4.8 × 10–13.  An aqueous solution of NaH2PO4 therefore would be
◦ neutral
◦ basic
◦ acidic

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).
