WebIn contrast, the hydrogen carbonate ion (HCO3-(aq)), with its single negative charge, has lower surface charge density than the carbonate ion and is a considerably weaker base. It exerts a feeble attraction for protons and the pH of the solution only reaches a pH of ca. 8.3. WebIt is all probabilistic. If there are many H+ ions, there is a greater chance that they will bump into HCO3- ions, forming greater quantities of H2CO3. If there is a "shortage" of H+ ions, then there will be a smaller quantity of …

Webcarbonic acid, (H2CO3), a compound of the elements hydrogen, carbon, and oxygen. It is formed in small amounts when its anhydride, carbon dioxide (CO2), dissolves in water. CO2 + H2O ⇌ H2CO3 The predominant species are simply loosely hydrated CO2 molecules. Carbonic acid can be considered to be a diprotic acid from which two series of salts can … La concentration en bicarbonate dans le sang est entre 22 et 26 mmol/L . Le caractère amphotère du bicarbonate (sa place intermédiaire dans l'équilibre), lui fait jouer un rôle de tampon. Cette fonction de tampon des bicarbonates existe notamment dans le sang, avec un rôle très important pour le maintien du pH (cf. Homéostasie). De nombreux organes interviennent dans la régulation du taux des bicarbonates, donc du pH : … northern gp federation
