Some freedivers hyperventilate (breathe rapidly and deeply) before diving. Hyperventilation can change the concentration of CO 2 CO2 in the blood and may increase the length of time that a person feels like he or she can hold his or her breath. How does hyperventilation affect blood pH?

Explanation:

It is a state of breathing process when a person start breathing very fast . When a person is under excessive stress or he is  paniky or he suffers from anxiety , he start breathing fast . Fast breathing results in excessive loss of carbon dioxide in the body.

Carbon dioxide forms acidic solution when dissolved in water . When level of carbon dioxide reduces in the blood , it becomes less acidic . In other words it becomes more basic. Therefore the level of pH of blood  is  increased .

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
