Question

What happens to the blood's pH as blood CO2 levels fall?
A)pH becomes more acidic.
B)Bicarbonate ions absorb the hydrogen ions.
C)pH increases.
D)pH decreases.

Accepted Answer

As blood CO2 levels fall, less carbonic acid is formed, leading to a decrease in hydrogen ion concentration, which causes the pH to increase, making the blood more alkaline.
