Bicarbonate can react with hydrogen ions to form carbonic acid, which combines with water to produce carbon dioxide and more water. The carbon dioxide is expired through the lungs thus helping maintain pH equilibrium in the body.

H20 + CO2<------->H2C03<------->H+ + HC0-3

Water + Carbon Dioxide combine under the influence of the enzyme Carbonic Anhydrase to form Carbonic Acid, which then spontaneously disassociates to form Hydrogen + Bicarbonate Ion.

as well as the reverse:

Hydrogen + Bicarbonate ions combine to form Carbonic Acide which under influence of Carbonic Anhydrase then forms water + Carbon Dioxide.

Bicarbonate itself (HCO3-) is NOT a buffer but a single compound.

A buffer is always a mixture of a weak acid and its conjugated (mono-protonated) weak base.

Possible reactions of bicarbonate (HCO3-) in water:

  • as weak acid: HCO3- <--> H+ + CO32-
  • as weak base (not conjugated!): HCO3- + H+ <--> H2CO3

Reading this carefully will bring into mind the two possible buffering mixtures:

  • bicarbonate/carbonate buffer: HCO3- (acid) and CO32- (conjugated base of HCO3-)
  • carbonic acid/bicarbonate buffer: H2CO3 (acid) and HCO3- (conjugated base of H2CO3)

The buffer system in blood is formed by?

The buffer system that operates in blood plasma is the bicarbonate buffering system. The chemical equation for this system is the following CO2 + H2O &lt;--&gt; H2CO3 &lt;--&gt; HCO3- + H+.


Which buffer system acts the fastest?

bicarbonate buffer is instant, followed by respiratory, renal, and phosphate.

Compare the buffer system in the whole blood?

The blood contains buffers like bicarbonate and phosphate buffers. The bicarbonate buffer is by far, the most important.


How does the Blood buffer system work?

Buffer systems help to maintain constant plasma pH. There are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, the bicarbonate buffer system is the most predominant. Buffer Systems function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3


What are the buffer system of the blood?

The most important buffer for maintaining acid-base balance in the blood is the carbonic acid-bicarbonate buffer.
