The definition of an acid is commonly known as a substance which can produce hydrogen ions (Hydronium ions to be more precise) in solution. However, the currently more 'correct definition' of an acid is the Bronsted-Lowry definition which states that an acid is a substance which donates protons (i.e. hydrogen ions).
Carbonic acid, as the name implies, is an acid which can ionise in aqueous solution to form bi-carbonate ions and hydrogen ions. In other words, carbonic acid ionises in solution to give up a proton (hydrogen ion) and produce bi-carbonate ions.
H2C03 <-> H+ + HCO3-
However, bicarbonate ions can act as a base or an acid according to Bronsted-Lowry definition as bi-carbonate ions can accept or donate protons (hydrogen ions). We call these substances which can accept or donate protons: Amphiprotic substances. Thus, bicarbonate ion is an amphiprotic substance because it can act a either a base or an acid.
Bi-carbonate ions acting as an acid:
HCO3- <-> H+ + CO32-
Bi-carbonate ions acting as an base:
HCO3- + H+ <-> H2CO3
What else can I help you with?
Does CO2 dissolve in water to form an acid or a base?
When carbon dioxide (CO2) dissolves in water, it forms carbonic acid, not a base.
Is CO2 a base?
It's not a base,it's an acid. CO2 in the air is actually neither a base or an acid. However, when it comes into contact with water it reacts to become H2CO3, which is an acid.
C02 plus H20 is a base?
No, it forms an acid, H2O + CO2 --> H2CO3 (carbonic acid)
Is CO2 an acid or a base in chemical reactions?
CO2 is neither an acid nor a base in chemical reactions. It is a nonpolar molecule that does not ionize in water to produce H or OH- ions, which are characteristic of acids and bases, respectively.
Is CO2 a base acid or salt?
When CO2 is dissolved with water creates H2CO3 which is a acid

Is bottled soda an acid or a base?
soda is acidic because it has CO2 and carbonate
Is CO2 a base acid or salt?
When CO2 is dissolved with water creates H2CO3 which is a acid
Is CO2 a bronsted lowerybase?
No, CO2 is not a Bronsted-Lowry base. It is a non-metal oxide that reacts with water to form carbonic acid, H2CO3, and can act as an acid in some chemical reactions.
Is CO2 a acid?
No, CO2, or carbon dioxide, is not an acid.
What is the reason for baking soda to be a base?
Baking soda reacts with acid, so it's a base: HCO3- + H+ --> H2O + CO2
What gas is formed when a base reacts with an acid?
No gas. Acid + base --> salt + water only
What acid is produced by bubbling co2 into water?
CO2 + H2O --> H2CO3Carbonic acid.=========
Does acid concentration change if it is left standing?
It can if left standing and the water evaporates, making it stronger. Bases are more likely to change however, due to CO2 in the air. When CO2 combines with water, it forms the acid H2CO3, which is carbonic acid, which tends to neutralize the base.
