Question

Carbon dioxide readily combines with water to create carbonic acid, which in turn

reversibly dissociates into hydrogen ions and bicarbonate ions. If you increase the
concentration of carbon dioxide in a system such as the ocean, or human blood,
what would happen to the pH of the system?
O
A. It would initially increase, then decrease.
O
B. It would remain completely unchanged.
o
C. It would increase.
O D. It would decrease.

Answer 1

C. It would increase.

Step-by-step explanation:

Increase in concentration of carbon dioxide results in high hydrogen ion concentration in the blood or ocean increases the pH and decreases the ability of hemoglobin to bind with oxygen.

An increase in pH leads to the acidity of the blood that stimulated brain cells to produce faster and deeper breathing to compensate for the shortage of oxygen in the body.

Hence, the correct answer is "C. It would increase".
