Answer to Question 1

ANS: B
If an electrode is placed in such a solution, positive ions migrate to the negative pole of the elec-trode. These ions are called cations.

Answer to Question 2

ANS: D
The ratio of HCO3 to carbonic acid in healthy individuals is maintained near 20:1; this results in a pH of close to 7.40. HCO3 stores are evenly divided between intracellular and extracellular compartments.
