1794, from French carbonate "salt of carbonic acid" (Lavoisier), from contemporary Latin carbonatem "a carbonated (substance)," from Latin carbo (see carbon).
- 1805, "to form into a carbonate," from carbonate (letter.) by impact of French carbonater "change into a carbonate." Indicating "to impregnate with carbonic acid fuel (for example. carbon dioxide)" is from 1850s. Related: Carbonated; carbonating.
The term alkali is employed in a technical sense for the carbonate and hydrate (of sodium), but since in the Leblanc process the manufacture of sodium sulphate necessarily precedes that of the carbonate, we include this as well as the manufacture of hydrochloric acid which is inseparable from it.
