WebH2CO3 is considered an acid because it ionizes in H+ and HCO3-. Some of the HCO3- will bond with water and form OH- and H2CO3 again. This is an equilibrium. But If we have only one HCO3- that didn't yet bonded to water and formed H2CO3 again, we will have more H+ in the medium, and it will be acid. WebHowever, the incorporation of sulfate ions into bioapatite should also be taken into account. Indeed, it has been reported that SO 4 2-can substitute HPO 4 2-ion (both ions having the same valence and very similar ionic radius) [40].
