Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An increase in CO2 causes an increase in blood pH.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In the presence of an excess of CO2, there will be a shift to carbonic acid, ultimately causing the generation of hydrogen cations and bicarbonate anions. It is with this increased production of hydrogen ions that bodily pH will begin to decrease, causing acidosis from acidemia.

Detailed explanation-2: -As mentioned, when carbon dioxide is dissolved in water, the release of hydrogen ions in carbonic acid is what lowers the pH. As CO2 levels increase around Earth, the amount of dissolved CO2 also increases, which increases the amount of carbonic acid, therefore decreasing the pH.

Detailed explanation-3: -Respiratory acidosis occurs when the lungs can’t remove enough of the carbon dioxide (CO2) that the body produces. Excess CO2 causes the pH of your blood and other bodily fluids to decrease, making them too acidic.
