During transport of carbon dioxide blood does not become acidic due to:

Explanation

The bicarbonate buffering system of blood is an important buffer system in the acid-base homeostasis of living things, including humans. As a buffer, it tends to maintain a relatively constant plasma pH and counteract any force that would alter. In this system, carbon dioxide CO2 combines with water H2 O to form carbonic acid H2 CO3 , which in turn rapidly dissociates to form hydrogen ions H+ and bicarbonate HCO3 as shown in the reactions below.CO2 +H2 O⇄H2 CO3 ⇄HCO3− +H+The carbon dioxide - carbonic acid equilibrium is catalyzed by the enzyme carbonic anhydrase; the carbonic acid - bicarbonate equilibrium is simple proton dissociation/association and needs no catalyst. Any disturbance of the system will be compensated by a shift in the chemical equilibrium.
