At first the carbonic acid amide (1) reacts with the sodium hypochlorite.
Also, the increase in residue biomass with time likely stimulated microbial activity and therefore increased the production of carbonic acid, a by-product from microbial respiration.
Secondary porosity development (alarmingly called decompaction!) is thought to result from carbonate solution by carbonic acid formed by decarboxylation during early stage hydrocarbon generation.
Carbonic acid as the host signal for the development of parasitic stages of nematodes.
During this period microbial activity is at its lowest because of low soil temperatures and therefore the production of carbonic acid is likely at its minimum.
I do not like imbibing carbonic acid gas, either in mineral waters or in anything else.
Another thing is carbon dioxide, which is what we used to call carbonic acid gas, and it is very unpleasant.
The nostrils and mouths of human beings are such that one does not die from carbonic acid gas.
