Bicarbonate (HCO 3) is a vital component of the pH buffering system of the human body (maintaining acid–base homeostasis). 70%–75% of CO2 in the body is converted into carbonic acid (H2CO3), which is the conjugate acid of HCO 3 and can quickly turn into it. With carbonic acid as the central intermediate … Meer weergeven In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogencarbonate ) is an intermediate form in the deprotonation of carbonic acid.
