Inorganic carbon

The molecule of Carbon dioxide CO₂ exists with the gas state in the terrestrial atmosphere. A certain quantity of this CO₂ dissolves in oceanic and continental water, and part of CO₂ dissolves reacts with the molecule of Eau to form carbon Dioxide H₂CO₃ following the reaction

H₂0 + CO₂ (dissolves) <===> H₂CO₃

Then H₂CO₃ (carbonic Dihydrogénocarbonate =acide) being a diacid, yields its two Proton S in the measurement of the constant of acidities of the acido-basic couples (H₂CO₃/HCO₃^-) and (HCO₃^-/CO₃^2-) and of the initial composition in acido-basic Soluté S of water according to the equations

H₂CO₃ + H₂O <===> HCO₃^- (ion Hydrogénocarbonate = Bicarbonate) + H₃O⁺ (Ion hydronium = Proton hydrated)

and

HCO₃^- + H₂O <===> CO₃^2- (ion carbonates) + H₃O⁺

However it is that in the Sea water, this system of Carbonate S is present in great quantities and in proportions such as it plays a part fundamental Tampon in the acidity of the oceanic water (pH 8,1-8,4) which he makes it possible to make very stable. This rate of carbonates (and Borate S, to be exact) is called the Alcalinité or Titer Alcalimétrique Complet (TAC, measured in French degrees, or KH measured in °allemands; there exist other units. Best is of speaking in Ppm, or Parts Per Million). This pH allowed " quantities; geological " of Test S Calcareous S of Protozoon S Plankton ic to form sedimentary rocks limestones primarily made up of a Crystal of calcium Carbonate and magnesium (mixture which one calls limestone): the stone of Paris, the Marble, etc All this chemistry is traditionally included in the inorganic Chemistry, i.e. inorganic, although there are obviously many points on which that is not justified. Thus, one will be able to qualify the carbon contained in carbon dioxide, the carbon dioxide, the hydrogénocarbonate and carbonates it, of inorganic carbon. It is also valid for carbon Diamant and the others allotropic varieties of the Cristal of carbon.
