We know that carbon dioxide
reacts with water to form "carbonic acid." However what we really
call as carbonic acid is not the weak acid H2CO3; H2CO3 does not even exist in
aqueous solution. What really we call as carbonic acid is simply CO2 dissolved
in water which is in equilibrium with small amounts of H+ and HCO3-. HCO3^- is
the intermediate substance between CO2 and CO3^2-. By adding OH- to HCO3^- we produce
CO3^2-. Adding H+ to HCO3 produces CO2.
CO2(aq) + H2O(l) <==> H+ + HCO3^- ........
carbonic acid .... midrange pH values
HCO3^- + OH- <==> CO3^2- + H2O(l) ....... formation of
carbonate ion .... basic
HCO3^- + H+ <==> CO2(g) + H2O(l) .......... formation
of carbon dioxide .. acidic
Acid: H2CO3
Conjugate Base: HCO3-
Base: H2O
Conjugate Acid: H3O+
The equation is as follows:
H2CO3 + H2O <==> HCO3- + H3O +

Carbonic acid gas reacts with water to create carbonic acid. The so-called acid is not a weak acid H2CO3; H2CO3 isn't even in the solution. Acid is simply CO2 dissolved in water that is in balance with a small amount of H + and HCO3-.
Acid: H2CO3
The base of conjugation: HCO3-
Base: H2O
Conjugate Acid: H3O +
It has a molecular weight of 62,024 g / mol and a density of 1,668 g / ml. Carbonic acid is a weak and unstable acid, which partially dissociates in water in hydrogen ions (H +) and bicarbonate ions (HCO3-) with pKa 3,6.
If you consume a food or drink that contains in H2CO3 (carbonic acid), it can affect the acidity in the blood becomes more acidic than it should so that the pH in the blood decreases. This situation is called acidosis.
The effect of this is that breathing becomes deeper and faster because the body tries to reduce excess acid in the blood by lowering carbon dioxide.
