HCO3 (bicarbonate)
In聽inorganic chemistry,聽bicarbonate聽(IUPAC-recommended nomenclature:聽hydrogencarbonate) is an intermediate form in the聽deprotonation聽of聽carbonic acid. It is a聽polyatomic聽anion聽with the chemical formula聽HCO3. Bicarbonate serves a crucial biochemical role in the physiological聽pH聽buffering聽system. The term “bicarbonate” was聽coined聽in 1814… Read more.
