The residue of air left after burning, in fact a mixture of nitrogen and carbon dioxide , was sometimes referred to as "phlogisticated air", having taken up all of … Phlogiston theory states that phlogisticated substances contain phlogiston and that they dephlogisticate when burned, releasing stored phlogiston which is absorbed by the air. Growing plants then absorb this phlogiston, which is why air does not spontaneously combust and also why plant matter burns as well as it does. Thus phlogiston accounted for combustion via a process that was the inverse of that of the oxyg…
