| Hazard Information | Back Directory | [Chemical Properties]
colourless aqueous solution | [Physical properties]
Carbonic acid has the formulaH2CO3 (equivalently
OC(OH)2). It is also a name sometimes given to solutions
of CO2 in water | [Uses]
Carbonic acid (H2CO3) is produced by dissolving carbon dioxide in water. When formed
under pressure, it is the gas used in carbonated drinks. In nature, it dissolves the limestone in
caves, resulting in the formation of stalactites and stalagmites. It is corrosive as are other acids,
although it is considered a rather weak acid. | [Uses]
Carbonic acid is used in the
manufacture of soft drinks, inexpensive and artificially
carbonated sparkling wines, and other bubbly drinks. | [Definition]
ChEBI: Carbonic acid is a carbon oxoacid and a chalcocarbonic acid. It has a role as a mouse metabolite. It is a conjugate acid of a hydrogencarbonate. |
