What does azotic mean?
Azotic is a chiefly historical adjective meaning containing or relating to nitrogen. It derives from 'azote', the name given to the gaseous element by Antoine Lavoisier and other early chemists, from Greek roots suggesting lifelessness — since nitrogen does not support combustion or respiration. In late-eighteenth- and nineteenth-century chemistry, terms such as azotic acid and azotic compounds appeared regularly in textbooks and treatises, describing what we would now call nitrogen-bearing substances such as ammonia and nitrates. As chemical nomenclature standardised around names derived from 'nitre', the adjective fell out of use, replaced by the modern term 'nitrogenous'. Today azotic survives almost entirely in old scientific literature, making it a word of interest to historians of science rather than to working chemists. It should not be confused with 'azoic', which describes conditions entirely without life.
adjectiveOf, relating to, or containing nitrogen; an older chemical term describing substances associated with the element that was once called 'azote'.
- Relating to or containing nitrogen (chiefly in historical chemical usage).
"Early chemists classified ammonia as an azotic compound long before the element acquired its modern name, nitrogen."
"The treatise described several azotic salts then known to analytical chemistry."
"In eighteenth-century French nomenclature, air was thought to consist of a vital portion and an azotic portion."
Before chemists settled on 'nitrogen', they called the element 'azote' — from Greek for 'lifeless' — so calling something azotic once literally meant it belonged to the lifeless gas.

Etymology of azotic
Azotic comes from 'azote', the name coined by French chemists in the 1780s for the element now called nitrogen, ultimately built on Greek roots meaning 'lifeless' because the gas extinguished flame and did not sustain breathing. The English adjective azotic formed directly from azote in the same period. When international chemical nomenclature later adopted names based on 'nitre' (potassium nitrate), nitrogen superseded azote and nitrogenous replaced azotic, leaving the latter as a relic of historical usage.
How azotic is actually used
A largely obsolete or historical term of chemistry. Modern scientific writing uses 'nitrogenous' or simply 'containing nitrogen' instead. Encountered mainly when reading older chemistry texts.
Easily confused with azotic
'Azotic' refers to compounds containing nitrogen, while 'azoic' means devoid of any life, as in the Precambrian 'Azoic era'.
'Azote' is a noun — Lavoisier's original French name for the element nitrogen — whereas 'azotic' is the adjective describing things containing it.
