carbonic

It turns out that the carbon dioxide gas reacts with seawater to make carbonic acid.

Neither can there be any doubt that water and carbonic acid are the only substances from which these elements can be obtained.

Heavy and continued rain diminishes the quantity of carbonic acid, by dissolving and carrying it down into the soil.

And phosphate of lime is also taken up by water containing carbonic acid, or even common salt in solution.

In the flowers, both by day and night, there is a constant absorption of oxygen, and evolution of carbonic acid.

Each person exhales about fourteen cubic feet of carbonic acid gas in an hour.
