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 : … WebBộ câu hỏi trắc nghiệm hóa học 11 cánh diều.
