  • [[Reference ranges for blood tests]], comparing blood content of bicarbonate (shown in blue at right) with other constituents.
  • CO<sub>2</sub> produced as a waste product of the oxidation of sugars in the mitochondria reacts with water in a reaction catalyzed by [[carbonic anhydrase]] to form H<sub>2</sub>CO<sub>3</sub>, which is in equilibrium with the cation H<sup>+</sup> and anion HCO<sub>3</sub><sup>−</sup>. It is then carried to the lung, where the reverse reaction occurs and CO<sub>2</sub> gas is released. In the kidney (left), cells (green) lining the proximal tubule conserve bicarbonate by transporting it from the glomerular filtrate in the lumen (yellow) of the nephron back into the blood (red). The exact stoichiometry in the kidney is omitted for simplicity.

bicarbonate         
[b??'k?:b?ne?t, -n?t]
¦ noun
1. Chemistry a salt containing the anion HCO3-.
2. (also bicarbonate of soda) sodium bicarbonate.
Bicarbonate         
·noun A carbonate in which but half the hydrogen of the acid is replaced by a positive element or radical, thus making the proportion of the acid to the positive or basic portion twice what it is in the normal carbonates; an acid carbonate;
- sometimes called supercarbonate.
Bicarbonate         

In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogencarbonate) is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula HCO

Bicarbonate serves a crucial biochemical role in the physiological pH buffering system.

The term "bicarbonate" was coined in 1814 by the English chemist William Hyde Wollaston. The name lives on as a trivial name.

1. Heating water causes the bicarbonates to precipitate out.
2. Dissolved bicarbonates of calcium and magnesium, which make water hard, also depress the water‘s freezing point and slow its rate of cooling compared to softer water that has less of the bicarbonates.
