In what kind of bottle is hydrogen peroxide kept? Why?

It is kept in a dark plastic or glass bottle. H2O2 is decomposed dy light into hydrogen and oxygen gas, therefore, you will always find it in a dark bottle.\nThe bottle also needs an airtight seal because the decomposition takes place in the dark also (but at a much slower pace) so by trapping the gases formed, the decomposition is stopped and the H2O2 is preserved (which is why we bottle it in the fist place)

hydrogen peroxide slowly breaks down into water and oxygen. blood contains a catalyst called catalase. when the hydrogen peroxide comes in contact with catalase, it speeds up the breakdown. you are basically seeing oxygen breaking apart from water. sunlight also speeds up the reaction. (thats why it comes in a brown container);)

The symbols on the bottom indicate the type of plastic. This information is (theoretically) used for recycling purposes. Not all plastics can be dumped togeter for recycling.\n\nIf the bottle hasn't been used there shouldn't be a problem. I would not recommend a used bottle unless it has been boiled, and personally wouldn't use it even then.

H-O-O-H\n\nThere are NO double bonds in hydrogen peroxide.  If there were, the molecule would be charged.  If you don't believe me, check the link.

I've been using a plastic water bottle again and again (for drinking water from), and I've been fine, however if you are worried, then wash it out properly between uses (as in with detergent and hot water).  We use glasses again and again, and this is considered ok, so why not plastic water bottles?

a dark bottle is used b/c light will destroy the peroxide...it's very light sensitive.\n\nas for the second question...i have no clue.

you can also take one part hydrogen peroxide to one part water and use it like a mouth wash. it whitens with out "bleaching" which is really bad for your enamel. it's also a lot cheaper.

if you want to try a home remedy, then monostat or canesten, you can use a solution of peroxide and water, equal parts. also plain yogurt insert and rubbed around outside of area, yogurt is a yeast based product so it mimics and ultimately kills the bacteria from infection.

Go to the store and buy a bottle of 3% hydrogen peroxide, pour some into a 150ml beaker and you are done.

Never use peroxide cause it is a cancer causing agent. It changes the molecules in your skin

actually, a lot of organic and chemical products are kept in dark colored glass or bottles because the ultra violet rays in sunlight, over time, weaken the chemical properties.

because when its in the bottle it stays moist. glue holds together as it drys...

The oxygens are bonded together with the one hydrogen bonded to each oxygen.  It hydrogen peroxide and has 18 electrons

Superoxide is a reactive anion and free radical, formally O2-. It is produced most easily by burning rubidium or caesium in oxygen. Other superoxides, including potassium superoxide, are also known. It has an unpaired electron, is not particularly stable, and spontaneously decomposes into peroxide and oxygen over time. In phagocytes, superoxide is produced in large quantities by the enzyme NADPH oxidase for use in oxygen-dependent killing mechanisms.\n\nHydrogen peroxide (H2O2) is a clear liquid, slightly more viscous than water. It has strong oxidizing properties and is therefore a powerful bleaching agent that has found use as a disinfectant, as an oxidizer, and in rocketry (particularly in high concentrations as high-test peroxide (HTP) as a monopropellant), and in bipropellant systems.

hi!\nYou can keep hygroscopic chemical in a bottle with tightly caped and seal with teflon tape. Store the bottle in a box containing sodium sulphate/descicating material.

Unless you are talking beauty supplies rather than chemistry.\n\nThen you mix the peroxide with bleach powder or dye to activate them.  10 volume is the weakest, therefore slowest.  50 volume is the strongest, fastest.
