Certaines eaux souterraines contiennent aussi des carbonates (CO3-2) et les eaux industrielles peuvent contenir d'autres bases faibles comme de l'ammoniaque et même des bases fortes comme les alcalis (OH-). Leur pH est alors supérieur à 8,3. solar panel tracking mount https://thebodyfitproject.com

Can we calculate bicarbonate concentration from pH

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).
