Discussion Overview

The discussion revolves around the question of whether any substances can release oxygen when burned, particularly in relation to carbon monoxide. Participants explore the nature of combustion, potential chemical reactions, and the possibility of using plants to generate oxygen during burning.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions if there are substances that release oxygen when burned instead of carbon monoxide.
  • Another participant asserts that combustion, by definition, does not produce oxygen, as it is an oxidation reaction.
  • A different viewpoint suggests that while combustion typically does not release oxygen, certain reactions with oxidizers can produce oxygen, citing examples like chemical oxygen generators and shuttle boosters using ammonium perchlorate.
  • One participant mentions that sodium can burn in chlorine and that more reactive compounds could potentially release oxygen, although this may not be classified as combustion.
  • There is a repeated inquiry about whether a plant could be burned to release oxygen that would neutralize carbon monoxide.
  • Another participant states that carbon monoxide can burn in normal air, implying that proper combustion conditions can prevent its formation.
  • One participant expresses confusion regarding the relationship between proper burning and carbon monoxide production.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the original question. There are multiple competing views regarding the nature of combustion and the potential for oxygen release, with some participants asserting that combustion does not produce oxygen while others suggest specific chemical reactions that could.

Contextual Notes

Some claims rely on specific definitions of combustion and may depend on the context of the reactions discussed. The discussion includes assumptions about the nature of combustion and the conditions under which carbon monoxide is produced.

is there anything that gives off oxygen when burning rather than carbon monoxside? What I am wondering is if there is something that when burned releases oxygen that would combine with carbon monoxide and either neutralize the carbon monoxside or over ride it in some wayy
 
Chemistry news on Phys.org
Combustion is by definition, a rapid, exothermic oxidation reaction, so no.
 
That's not exactly true. Though that's the definition of "combustion", it does not implly starting with pure oxygen and ending with something other than oxygen. If the oxidizer is a chemical and the reaction has an overabundance of oxygen, it can, indeed release oxygen in the reaction. This is how oxygen generators in firefighting equipment work: http://en.wikipedia.org/wiki/Chemical_oxygen_generator

The shuttle boosters use ammonium percholrate as an oxidizer, which is NH4ClO4 http://en.wikipedia.org/wiki/Ammonium_perchlorate
 
Sodium can "burn" in chlorine with a flame.

You can generate oxygen by replacing it with a more reacting compound like fluorine out of it's oxides or compound. The reaction generates heat but I doubt it that you could call that combustion.

Some chemicals are unstable and could release O2 like russ said.
 
what I am thinking of and should have made clear is that I am wondering if there is a plant of some sort that when burned would give off oxygen that would combine with the carbon monoxide with the result that the carbon monoxide would be neutralized.

That no. But CO burns quite well in normal air.
 
...and if things are burned properly, CO isn't a product of combustion anyway. I'm still confused...
