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
