When exposed to the air it attracts humidity and carbonic acid.
The quantity of lime must be proportional to the carbonic acid in the soda.
The carbonic acid gas is produced from the combustion of coke.
The products of the combustion are water and carbonic acid gas.
These are ammonia, carbonic acid, nitrous oxide, and chlorine.
The ebullition is due mainly to the emission of carbonic acid gas.
They obtain it chiefly from the air, in the form of carbonic acid gas.
What becomes of the carbonic acid gas which is produced by combustion?
What is the effect of carbonic acid gas upon the human system?
Because carbonic acid gas is forced into the water by pressure.
