sodium Posted October 16, 2004 Share Posted October 16, 2004 I put some hydrogen peroxide in a container in my kitchen freezer to get more pure h2o2. And without thinking if the gases are harmful . Someone please tell if the it is ok. Link to comment Share on other sites More sharing options...
Skye Posted October 16, 2004 Share Posted October 16, 2004 I imagine it's the hydrogen peroxide fuming. Avoid breathing in the fumes because they'll sting. Link to comment Share on other sites More sharing options...
sodium Posted October 16, 2004 Author Share Posted October 16, 2004 thank you. but if I keep it in a closed container will it still be alright the next day to eat the food i had in my freezer? Link to comment Share on other sites More sharing options...
Skye Posted October 16, 2004 Share Posted October 16, 2004 Your food should be fine. Link to comment Share on other sites More sharing options...

YT2095 Posted October 16, 2004 Share Posted October 16, 2004 it shouldn`t produce Any fumes at all? Link to comment Share on other sites More sharing options...
sodium Posted October 17, 2004 Author Share Posted October 17, 2004 YT2095 it shouldn`t produce Any fumes at all? I thought it would fume for some reason, but it didn't and know I know why. I am new to chemistry and all this test tube thingies and the measurments. I cant wait till I have my first chemistry class next semester. And no I am not making AP. I have so little knowledge in chemistry I would probaly kill myself. Link to comment Share on other sites More sharing options...
budullewraagh Posted October 17, 2004 Share Posted October 17, 2004 it doesnt fume because there are no possible gases released; hydrogen peroxide is a liquid at room temperature, and freezes at -11 celcius. freezing doesn't cause it to decompose, but heating does, as it will yield diatomic oxygen and water Link to comment Share on other sites More sharing options...
Gilded Posted October 17, 2004 Share Posted October 17, 2004 "but heating does, as it will yield diatomic oxygen and water" (2)H2O2 -> (2)H2O + O2 ? I always thought heating hydrogen peroxide is something I wouldn't like to do. Link to comment Share on other sites More sharing options...
budullewraagh Posted October 17, 2004 Share Posted October 17, 2004 it is, as the rapid expansion of diatomic oxygen yields quite a few atmospheres Link to comment Share on other sites More sharing options...
Gilded Posted October 17, 2004 Share Posted October 17, 2004 Yipes! It doesn't have too much ignition risk, because of the water vapor though... or does it? Link to comment Share on other sites More sharing options...
budullewraagh Posted October 17, 2004 Share Posted October 17, 2004 well, it depends on the concentration. if you have 70% or more and you add a very small amount of any sort of reducing agent, the reducing agent will oxidize and some peroxide will reduce, but the energy released by this will activate the decomposition of the rest of the peroxide Link to comment Share on other sites More sharing options...
