Discussion Overview

The discussion revolves around the stability of hydrogen peroxide (H2O2) when diluted in water and stored at temperatures between 5-10 degrees Celsius. Participants explore the duration of stability and practical implications for use, particularly in cleaning applications.

Discussion Character

  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant questions whether H2O2 remains stable when diluted in water at 5-10 degrees and for how long.
  • Another participant asserts that H2O2 does not remain stable under these conditions.
  • A participant shares their experience of mixing a 6% solution of H2O2 for cleaning, expressing concern about the reliability of that concentration over a few hours.
  • In response, another participant suggests that the 6% solution will last for a few hours but notes that the concentration will decrease as it reacts with the surface being cleaned.
  • A participant provides anecdotal evidence from their previous experience with H2O2, mentioning that their company stored a 1% solution for up to four days at room temperature and warns about the risks associated with high concentrations.

Areas of Agreement / Disagreement

Participants express differing views on the stability of H2O2 in water at the specified temperatures, with no consensus reached on the duration of stability or the implications for practical use.

Contextual Notes

There are unresolved questions regarding the specific conditions affecting H2O2 stability, including concentration levels and environmental factors. The discussion includes anecdotal experiences that may not generalize across different scenarios.

Does H2O2 stay stable once diluted in Water kept at 5-10 degrees. If so for how long?
 
Chemistry news on Phys.org
It doesn't.
 
I am attempting to clean a screen with H2O2 based on the manufacturers recomendations. I am mixing a 6% solution of H2O2 (50% conc) and water. I trust I should be able to count on 6% for a few hours! Am I wrong:(
 
It'll last that long. Don't cap it tightly. As the peroxide works on the stuff on the screen and the screen itself, the concentration will go down. You should see bubbles on the screen throughout the process.

My previous company produced it in batch quantities at 1% and stored it for a 4 days at the most at room temperature. It isn't that interesting at low concentrations however there are all sorts of problems with it at high concentrations - be certain to not get it on flammable surfaces e.g. wood and even leather shoes if you are wearing one even a few drips may cause it to catch fire.
