What is the relationship between CO2 and pH in the blood?

Hence, arterial CO2, carbon dioxide, through several independent biochemical mechanisms, can influence blood pH and cause respiratory alkalosis in patients with chronic diseases. CO2 also influences the viscosity of blood. Acute hyperventilation and arterial hypocapnia make blood more viscous.

Answer: Carbonic acid (H2CO3) is formed when carbon dioxide reacts with water to generate carbonic acid (H2CO3), which can dissociate to form a hydrogen ion (H+) and a hydrogen carbonate ion (HCO3-). Increasing the concentration of CO2 in the blood leads in more H+ ions and a lower pH.
