Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An increase in blood carbon dioxide levels is followed by a (an) ____ in hydrogen ions, and a (an) ____ in blood pH
A
decrease, decrease
B
decrease, increase
C
increase, decrease
D
increase, increase
Explanation: 

Detailed explanation-1: -Carbon dioxide influences the pH of blood by reacting with water to form carbonic acid (H2CO3), which can dissociate to form a hydrogen ion (H+) and a hydrogen carbonate ion (HCO3-). Increasing the concentration of carbon dioxide in the blood therefore results in more H+ ions and a lower pH.

Detailed explanation-2: -Answer and Explanation: When carbon dioxide levels increase in the blood, the pH levels will decrease due to the buildup of hydrogen ions. Increasing hydrogen ions will always decrease the pH level making the blood more acidic.

Detailed explanation-3: -The blood carries carbon dioxide to the lungs, where it is exhaled. As carbon dioxide accumulates in the blood, the pH of the blood decreases (acidity increases).
