How does the carbonic acid-bicarbonate buffer system of blood

Jul 02, 2009 · The main job of the carbonic acid/bicarbonate system is to regulate body pH. The lungs expel CO2, which raises pH, because hydrogen ions have to be consumed with bicarbonate ions in order to produce CO2 (then there are less hydrogen ions floating around). To prevent too many hydrogens from being lost, the kidneys remove excess bicarbonate ions.

In complex organisms, this carbon dioxide is released into the blood and transported to the lungs for exhalation. While in the blood, carbon dioxide reacts with water. The product of this reaction is a moderately strong acid, carbonic acid (pK a = 3.5), which becomes bicarbonate ion on the loss of a proton.

Why is carbonic acid a weaker acid than acetic acid?

Carbonic acid is not weaker than acetic. In fact, it is stronger, just as one might expect by looking at that extra electron-withdrawing substituent. The trouble is, carbonic acid is also pretty unstable. At any given moment, most of it exists as $\ce{CO2}$. This leads to much lower apparent acidity.
