Noun
a weak acid known only in solution; formed when carbon dioxide combines with water
Source: WordNetA 2016 theoretical report suggests that carbonic acid may have pivotal role in protonating various nitrogen bases in blood serum. Source: Internet
Addition of base to an excess of carbonic acid gives bicarbonate (hydrogen carbonate). Source: Internet
Care must be taken when quoting and using the first dissociation constant of carbonic acid. Source: Internet
Hence, the majority of the carbon dioxide is not converted into carbonic acid, but remains as CO 2 molecules, not affecting the pH. Source: Internet
In a similar manner, the weak unstable carbonic acid (H 2 CO 3 ) can lose one proton to form bicarbonate anion (HCO 3 − ) and lose a second to form carbonate anion (CO 3 2− ). Source: Internet
In solution this equilibrium between carbonate, bicarbonate, carbon dioxide and carbonic acid changes consonant to changing temperature and pressure conditions. Source: Internet
