WebWhen acids are added to a bicarbonate buffering system, the bicarbonate ions re-associate with H+ ions and re-form carbonic acid. This reduces H+ ion concentration (acidity) and … WebThis point is functionally set to pH 4.5. At this point, all the bases of interest have been protonated to the zero level species, hence they no longer cause alkalinity. In the carbonate system the bicarbonate ions [ HCO− 3] and the carbonate ions [ CO2− 3] have become converted to carbonic acid [H 2 CO 3] at this pH.
