Discussion Overview

The discussion centers around the feasibility of obtaining oxygen by breaking apart Carbon Dioxide (CO2) or Sulphuric Acid (H2SO4). Participants explore various methods and reactions, including electrolysis and chemical reactions, while considering both theoretical and practical implications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that it is possible to obtain oxygen from breaking apart Carbon Dioxide, referencing the role of plants in this process.
  • Others mention that electrolysis of water, with the addition of Sulphuric Acid to increase conductivity, can yield oxygen and hydrogen.
  • One participant proposes mixing bleach and hydrogen peroxide as a method to obtain oxygen, while cautioning against the dangers of inhaling peroxide vapors.
  • A magnesium flame is noted to burn in CO2, breaking it apart and consuming oxygen, but a later reply questions the utility of this reaction in terms of oxygen production.

Areas of Agreement / Disagreement

Participants express multiple competing views on the methods of obtaining oxygen, and the discussion remains unresolved regarding the effectiveness and safety of the proposed methods.

Contextual Notes

Some methods mentioned may depend on specific conditions or assumptions that are not fully explored, such as the efficiency of the reactions or the safety of the proposed experiments.

Is it possible, and if so how, to obtain oxygen by breaking apart Carbon Dioxide or Sulphuric Acid?

Ask any plant.

or Sulphuric Acid?
You can obtain oxygen and hydrogen by electrolysis of water,in the ratio 1:2,respectively.
. You will need to add some Sulphuric acid to increase conductivity.

A good way to get oxygen is mixing bleach and hydrogen peroxide. Fun little home experiment.

But, don't be stupid enough to breathe this, if any peroxide vapor is in the mix, it would be very dangerous for you.

A magnesium flame is able to continue burning in CO2 because the reaction is sufficiently energetic to be able to break apart CO2 and consume the oxygen while liberating carbon.

What's the use of this if we don't get Oxygen as a product here?
