H202 question
    #1276677 - 02/04/03 06:48 AM (14 years, 5 months ago)

Alright, I know that h202 breaks down. What i want to know is how long it takes before it happens so i know when to replace it.
Does anyone know?

at 60-70F room temperature, the half-life of peroxide is 10-20 days.
at warmer (incubator) temperatures, could be only half this, not that you'd need to have any H2O2 in there, i hope!

:tongue:

Hmm interesting..

I was curious to know how often i should replace the water/h2o2 in my spray bottle to make sure that there is still h2o2 in it!!!  :smile:

So once a week should do it!!

go to any major chain petstore and get this doohickey called a Misty Mate. It is a pump-pressure bottle with about 3 feet of tubing with a fine mist attachment. these things are completly opaque, insulated, and hold pressure. mix up your refridgerated h202 mixture and then fiil and pump up the pressure. this will make h202 keep for months (i have tested this by emptying the contents after 3 months into a graduated cylinder and placing a balloon (balloons!!!!) on top and watching it fill with the released o2) BTW, they sell these in the doggy toys/accessories as something to keep your dog cool in the summer. PetSmart always has them.

I've had peroxide thats been in the bottle for over a year and its still good. Light breaks down H2O2 also. H2O2 doesn't break down as fast if its in a cool completely dark place like in a opaque bottle like its sold in the stores.
