bicarbonate

 [bi-kahr´bon-āt]
any salt containing the HCO3 anion.
blood bicarbonate (plasma bicarbonate) the bicarbonate of the blood plasma, an important parameter of acid-base balance measured in blood gas analysis.
bicarbonate of soda sodium bicarbonate.

bi·car·bon·ate

(bī-kar'bon-āt),
HCO3-; the ion remaining after the first dissociation of carbonic acid; a central buffering agent in blood.

bicarbonate

A salt containing the anion HCO3-, which is the most important buffer in the blood, it is regulated by the kidney, which excretes it in excess and retains it when needed; it increases with ingestion of excess anti-acids, diuretics and steroids; it is decreased with diarrhoea, liver disease, renal disease and chemical poisoning.

Specimen
Bicarbonate is usually measured in serum as total CO2.
 
Ref range
24–26 Meq/L.

bicarbonate

HCO3 Nephrology A general term for any salt containing the anion HCO3–, which is the most important buffer in the blood; bicarbonate is regulated by the kidney, which excretes it in excess and retains it when needed; it is ↑ in ingestion of excess antiacids, diuretics, steroids; it is ↓ in diarrhea, liver disease, renal disease, chemical poisoning. See Blood gases.

In another study, chemical treatment of salseed meal with distilled water, acetic acid and sodium hydrogen carbonate reduced the content of tannins and therefore prevented their negative consequences (Mahmood et al., 2006).
A mixture of o-methoxy benzoic acid (0.01 mol 1.25g and m-cresol (0.01 mol, 1mL) was added to PPA (freshly prepared from 5mL) [H.sub.3]P[O.sub.4] and 8g [P.sub.2][O.sub.5]) heated with stirring at 70[degrees] C for 1hr., after which time it was poured into cold water, extracted with dichloromethane (200 mL) and washed with the sodium hydrogen carbonate solution (2 x 150 mL) and the resulting solvent dried with calcium chloride and them evaporated the solvent on the rotary evaporator.
The slurry packed column ion exchange capacity was measured converting the column to the sodium form using 0.01 M sodium hydrogen carbonate. The 0.01 M tartrate eluent was used for displacing sodium ions and the sodium amount found in the effluent was used to calculate the column ion exchange capacity.
Diethylphosphite (P(O)O[C.sub.2][H.sub.5])H, Fluka, 97%), N,N-dimethylformamide (DMF, Carlo Erba, p.a.), ethanol (Chimopar Romania, p.a.) tetrahydrofuran (Carlo Erba, p.a ), dimethylsulfoxide (Fluka, p.a.) sodium hydrogen carbonate (NaHCO3, Chimopar, p.a.), potassium carbonate (Chimopar, p.a.), methanol (Chimopar, p.a.), 1,2-dichloromethane (Chimopar, p.a.), diethyl ether (Chimopar, p.a.), tetraethylammonium iodide (Merck) were used without purification, and chloromethylated polysulfone (7.07% C1 GS= 0.98, 1-PSF) as mentioned in (23).
His product was a mixture of citric acid and sodium hydrogen carbonate, which effervesced when dissolved in water.
They argued for years over what it might be-sodium sulfate, hydrogen sulfate, sodium hydrogen carbonate, all these things that look more or less similar in this range of the spectrum.
In contrast the relative intensity of Eu-based emission bands varies with the concentration of chelating anions such as citrate and hydrogen carbonate, allowing ratiometric intensity-based sensing of these species.
A quart (or liter) of water from Baikal only contains 120 mg of salts, mainly hydrogen carbonates (the HC[O.sub.3]-ion).
This test measures carbon and hydrogen carbonates. Carbonates react with both acids and bases to buffer or minimize pH changes.
