WebIf there are many H+ ions, there is a greater chance that they will bump into HCO3- ions, forming greater quantities of H2CO3. If there is a "shortage" of H+ ions, then there will be a smaller quantity of H2CO3 being formed, … WebThe bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3 ), bicarbonate ion (HCO − 3 ), and carbon dioxide (CO 2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper metabolic function.
