Carbonic acid (Chem.),
an acid
H2CO3, not existing separately, which,
combined with positive or basic atoms or radicals, forms
carbonates. In common language the term is very generally applied
to a compound of carbon and oxygen, CO2, more
correctly called carbon dioxide. It is a colorless, heavy,
irrespirable gas, extinguishing flame, and when breathed destroys
life. It can be reduced to a liquid and solid form by intense
pressure. It is produced in the fermentation of liquors, and by
the combustion and decomposition of organic substances, or other
substances containing carbon. It is formed in the explosion of
fire damp in mines, and is hence called after damp; it is
also know as choke damp, and mephitic air.
