What to do with 6% hydrogen peroxide


Recently, I got a packet of 6% hydrogen peroxide. Strangely, it was sold in a packet (Not like the 3%, which was sold in a bottle). I need some of the 6% Hydrogen Peroxide for the synthesis of copper acetate. Does anyone know any synthesises that require hydrogen peroxide? Thanks

P.S. I know that the synthesis of copper acetate does not need hydrogen peroxide. I just want to accelerate the reaction.

You can use it to make ammonium iodide or use as oxidizer in organic iodinatins - but 6% could be too low.

You could also concentrate it and make it more useful

1.Disinfect stuff
2.Oxidise iron ii to iron iii
3.Make high test peroxide
4.Titrate it
5.Put it in an amber glass bottle and store it
6.Dissolve metals you wouldn't normally be able to in HCl or H2SO4
7.Make organic peroxides (don't do this)
8.Make piranha solution and watch a toothpick or wood chip get destroyed
There's many things one can do with hydrogen peroxide. Don't do 3 7 or 8 unless you know what you're doing




Nuclear physics is neat. It's a shame it's so regulated...

Now that I think about it, that's probably a good thing. Still annoying though.

You can try Fenton reaction. With 35% H2O2 it is more effective, but 6% is good enough. You can also make some metal peroxides. Sr, Ba and Zn peroxides are quite stable, unlike Ca and Mg peroxides. CuO2 is little bit challenging due to its high unstability, but if you make everything at low temperatures, it can be make.

itsallgoodjames: Piranha solution is mix of conc. sulfuric acid and 35% H2O2. 6% H2O2 containt too much water.

One could do 3 then 8.

put it in a freezer and make more concentrated stuff.



acid that repeat its qualities called "Periodic acid".

You could make sodium perborate with it, starting with sodium borate. Although, I am not sure whether 6% will be strong enough a concentration.

outer_limits: Very interesting, I didn't know that making iodides with H2O2 is possible.

second that, turn it into something more useful! you could reasonably get like 25% out of it

I use 3% or 6% hydrogen peroxide to make iodine from KI, make copper acetate, and for the iodine clock reaction, among other things. It is very useful.

I find the urea adduct is the most convenient for concentration of weak H2O2

Serine peroxide adduct is also good but less stable. It is sensitive to light. Is it possible to form an adduct with 3% without using a desicant of calcium chloride to concentrate the hydrogen peroxide.
