electrify water. There are books that have a detailed way of capturing the hydrogen and oxygen. Google up "electrolysis."

i set up a home electrolysis unit, ill post a bitmap pic of it later its simple to do

hope it works this time

 

[edit] yea it works, the electrodes are from D battery cells,and the rest is straight foward

Yes, get some normal everyday Hydrogen Peroxide from the chemists (pharmacy) the sort used to clean wounds.

open up an ordinary zinc/carbon battery, take out the black stuff and add it to your peroxide, it will react instantly giving zillions of bubbles, they will all be pure Oxygen :)

hmm

 

Generally electrolosis of water ends up with H2 and an oxide. hydroxide of the electrode, providing it is more reactive than H2 but if not a OH or O of the dissolved minerals. Remember pure water dose not conduct electricity so this will always happen with impurtities.

 

I tried to make I and KOH with KI once, but ended up with the Al electrodes hydroxidising

you would do :)

 

however for a neat electrolysis effect, for H and O2 use plain acidified water with carbon electrodes (the pencil lead from a carpenters pencil will work just nicely).

i used H2SO4 for the acid , i got it out of a car battery

also if you get hydrogen peroxide and add piece's of liver to it you get alot of oxygen produced as well which is much simpler easer to get hold of and quicker

I find normal Zinc/Carbon batts just as easy to get and alot less messy and gross! :))

 

of course the "environmentaly friendly" method would be to get a submerged pool type plant in the sunshine and capture the O2 from that under an up turned beaker :)

yes but you also might lose alot of the oxygen as well that way and its time consuming plus you wont get that much oxygen, and my method fairly enviromently friendly except for the hydrogen peroxide and you can always get a lot of liver even if it is gross

the question was:

 

Is there an easy way to produce oxygen at home?

and so, that IS an easy way, involves nothing complicated or dangerous, and will produce more oxygen than you`de think! I`ve done it :)

 

there`s no mention of scale either, thus, it`s yet ANOTHER way to produce the O2 :)

suprisingly, im having difficulty getting some graphite rods anywhere, i live in london, UK, can anyone suggest a shop which would sell them?

use the pencil leads burn of the wood and just use the pencil leads the thicker the pencil the better

why do you want them any way the electrolysis method doesnt work very well i have tried it

go to a welding shop (or even B&Q) and get some guaging rods, peel the copper foil off and hey presto, long carbon rods :)

Now that were talking about graphite, anyone know where to get pyrolytic graphite? You can make it levitate with four square shaped N40 NdFeB-magnets. :)

erm... nope?

 

if you find a source though, PM me, I use NIB magnets (just as good) :)

Use a lantern battery for the rods. That’s also the best way to get the MnO2.

 

Also the H2O2+MnO2 reaction is fun if you do it in a large flask with a rubber stopper with thin glass tube in it. It creates a nice stream of pure oxygen. Just light a match and put it over the stream and the flame resembles burning magnesium.
