Acidosis

 

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.

Some tunnels and in situ experiments provided that if groundwater included lots of calcium ions, carbonate ions, and bicarbonate ions, there would be calcium carbonate crystal on the inner surface of tunnel drainage pipes.
Formation of carbonate ion upon donation of the last proton by the bicarbonate ion;
Some patients have lung disease or other respiratory pathology that chronically limits their ability to achieve a minute ventilation high enough to keep their PaCO2 in a normal range and their body compensates for the high PaCO2 and low pH by allowing the kidneys to retain more of the alkalotic bicarbonate ion (HCO3-) to neutralize the acidic CO2 and bring the pH back toward the normal 7.4.
In engineering terms, alkalinity is expressed in units of milligrams per liter (mg [L.sup.-1]) of CaC[O.sub.3] [17], but in the present study alkalinity of water samples was calculated in millimoles of bicarbonate ions per [m.sup.3] of water (HC[O.sub.3.sup.-] mmol [m.sup.-3]) for better comparison of the amounts of different ions in the water samples.
Bicarbonate ion breakdown proceeds quickly under the conditions typically found with functioning cooling towers: modest water heating from tap water temperature to 95 [degrees]F, agitation that enhances surface release of carbon dioxide, and large air flow that readily accepts the release of [CO.sub.2].

It is believed that it is through this large pore that the bicarbonate ion is preferentially admitted to cancer cells rather than normal cells.

Bicarbonate ion is varies from 26 to 46 mg/l, 69 to 92 mg/l and 34.66 to 73.33 mg/l in the groundwater samples of during post, summer and premonsoon seasons respectively.
Total CO2 is the sum of the bicarbonate ion and the carbonic acid components of the acid-base equation.
The results shown in Table 3 indicate the relative fluctuation of pH values ranging between 6.55-7.72 and 77% of the water samples were within slightly alkaline range due to the presence of bicarbonate ions [14].
