Chapter 9, Problem 9.59PP

During stress or trauma, a person can start to hyperventilate. The person may then be instructed to breathe into a paper bag to avoid fainting.

${\text{CO}}_2\left(g\right)+{\text{ 2H}}_{\text{2}}\text{O}\left(l\right)\rightleftharpoons {\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\left(aq\right)+{\text{ HCO}}_{\text{3}}^{\text{-}}(aq)$

1. a. How does Mood pH change during hyperventilation?
2. b. In which direction will the bicarbonate equilibrium shift during hyperventilation ?
3. c. What is this condition called?
4. d. How does breathing into a paper bag help return the Mood pH to normal?
5. e. In which direction will the bicarbonate equilibrium shift as the pH returns to normal?
