Related to bicarbonate ion: hydrogen carbonate, Carbonic anhydrase, Hco3


A condition of decreased alkali reserve of the blood and other body fluids.



a change in the acid-alkaline balance of the organism as a result of insufficient removal and oxidation of organic acids (for example, beta-hydroxybutyric acid). Usually these products are rapidly removed from the body. In febrile diseases, intestinal disorders, pregnancy, starvation, and such, they are retained in the body; this is manifested in mild cases by the appearance of acetoacetic acid and acetone in the urine (so-called ketonuria). In severe cases (for example, diabetes mellitus) it may lead to coma. Treatment consists of removal of the cause of acidosis (for example, by administering insulin in case of diabetes); there is also symptomatic treatment—soda and an abundance of fluids taken internally.

Chemically speaking, carbonate system simply reflects the carbonate species present in an aqueous solution, these species are; carbonate ions, bicarbonate ions and the carbonic acid.
When comparing alkalinity (Figures 2 and 3) with concentrations of total nitrogen (Tables 1 and 2) and phosphorus (Tables 6 and 7) it can be seen that the concentration of bicarbonate ions was up to an order of magnitude higher.
In hard water containing bicarbonate ion a secondary reaction occurs at the anode:
It is believed that it is through this large pore that the bicarbonate ion is preferentially admitted to cancer cells rather than normal cells.
This value represents the bicarbonate ion concentration in the fluid corrected to a normal PCO2 of 40 mmHg and, in much the same way as base excess, describes the metabolic component of a patient's acid-base balance.
It splits carbon dioxide into bicarbonate ions and free protons, which stimulate the sour-sensing cells.
For shellfish and other organisms that have calcium carbonate shells and structures, the problem begins when atmospheric CO2 dissolves in seawater and creates carbonic acid that is then rapidly transformed into carbonate and bicarbonate ions in the water.
The RO membrane can then reject the bicarbonate ions.
The kidneys help control the body's acidity by absorbing filtered bicarbonate ions in exchange for chloride ions by secreting hydrogen ions.
Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport.
Bicarbonate ions in groundwater are derived from the carbon dioxide in the atmosphere, soil and solution of carbonate rocks which increases the alkalinity of water.
Scale inhibitor was mixed in anionic fraction at the required dose and the solutions were injected at 1:1 ratio so that the final concentration of calcium and bicarbonate ions in the solution was 300 ppm.
