Carbonic Acid
H2CO3, a weak dibasic acid that under normal conditions exists only in dilute aqueous solutions. Carbonic acid is formed when carbon dioxide dissolves in water: 
. Under normal conditions, the total amount of carbonic acid in a solution saturated with CO2 does not exceed 1 percent of the CO2 content. The dissociation constants are K1 = 4.0 × 10–7 and K2 = 5.2 × 10–11 at 18°C. Carbonic acid decomposes completely when its solutions are heated, liberating CO2. Depending on the basicity, the acid forms two series of salts. The neutral salts, known as carbonates, have the 
anion, and the acid salts, known as bicarbonates, have the 
anion.
