AI Thread Summary
Diluted hydrogen peroxide (H2O2) does not remain stable for long periods, even when stored at low temperatures (5-10 degrees Celsius). Users mixing a 6% solution from a 50% concentration can expect the solution to maintain its effectiveness for only a few hours. It is important not to seal the container tightly, as the concentration will decrease as the peroxide reacts with contaminants on surfaces, evidenced by bubbling during application. Historical data indicates that diluted H2O2 can be stored for a maximum of four days at room temperature, with lower concentrations being less effective. Caution is advised when handling high concentrations, as they can pose fire hazards if they come into contact with flammable materials.

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.
 

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
