  1. a salt of carbonic acid (containing the anion HCO3) in which one hydrogen atom has been replaced; an acid carbonate
  2. In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogencarbonate) is an intermediate form in the deprotonation of carbonic acid. Its chemical formula is HCO3−.
  3. Essential for regulating vital functions and one of the important buffers necessary to maintain normal acid-base balance in the body. ...
  4. The major form of alkalinity. In excessive amounts, in conjunction with calcium, may cause scale formation in water heaters.
  5. In medicine, bicarbonate usually refers to bicarbonate of soda (sodium bicarbonate, baking soda) a white powder that is common ingredient in antacids.
  6. A natural form of antacid or base that is normally excreted y the pancreas to neutralize the stomach acid as your food laves the stomach and enters the intestines. Bicarbonate is issolved in the blood and converted to citrate by the kidneys. common baking soda is chemically sodium bicarbonate.

  8. (bicarb), (sodium bicarbonate), (NaHCO3) - a substance that may be given the baby orally or intravenously to help neutralize excess acid in the blood.
  9. In acid-base determinations the concentration (in milliequivalents per liter) of the bicarbonate ion (HCO3^-) is calculated from the PCO2 and pH. Because it is also altered by both the respiratory and the metabolic components (see below under Physiology), it cannot be an ideal measure of either.
  10. The HCO3^- ion, or any salt formed with it such as sodium bicarbonate (NaHCO3)
  11. (baking soda), trisodium phosphate (TSP) and sodium hydroxide. Strong bases can cause serious skin
