Buying hydrogen peroxide >3% ??
I'm looking to purchase some hydrogen peroxide locally to make some copper chloride with. I'd like anything stronger than 15% as that is what I'm
going to dilute it to.
I've read a lot about h202 pool shock but cannot determine exactly what pool chemical I need. Is it sold in the pool chemical section as a liquid
"hydrogen peroxide" or is it a different chemical in powder form that creates hydrogen peroxide when mixed with water (that probably sound stupid to
those of you who know more about chemicals and phases of matter)??
Aside from online, what is the best source of getting this h202??
Thanks!

I can get 35% at my local health food store. It's expensive, however.

Great idea, there is one down the street from where I live. How much is it at your health food store??

I can't remember. I'll try to remember to check tomorrow.

I just remembered that I have some in the refrigerator. The price was $23.50/pint.

There is a health food store near where I live called Ambrosia. They sell a litre of 35% food grade hydrogen peroxide for $19.50 or so. They also have
a 4 litre size, but I'm not sure of the pricing. The hydrogen peroxide is marketed as "GoldTop Super Oxygen"
You can also find hydrogen peroxide in the pool section of some hardware stores. Look for something along the lines of "Chorine-free pool shock". I
know of a brand named BAQUACIL that sells 30% peroxide for pool shock; it can be found at a few hardware stores.

I used to buy the 40 volume stuff at Sally Beauty Supply. That comes out to a bit over 12%. Mixed with muriatic acid, it etched
copper printed circuit boards very aggressively (too aggressively for my purposes). Other beauty supply stores may carry it.
If you buy it locally, I'd suggest not buying large quantities of it, or looking like you're about to make explosives with it. Beauty
supply stores periodically find their way into the news when some guy tries buying a caseload of peroxide and fingernail polish
remover in the same purchase.

I found a liter of 50-60% peroxide in a pool store. (clark rubber Aussies)
It did however contain a small percentage of silver nitrate and cost $70 or so

HTH makes a 27% product that is available at most pool shops.
4 gallons runs right at $60.00

Just out of curiosity, what would the shelf life of something like HTH be? Since pools are massive (Volume wise) I'd expect you dump most of it in at
once, so would it last the months or years on a shelf in a lab?

I may be wrong, but I believe that these kinds of products almost always have some sort of stabilizer in them to slow the decomposition rate of the
peroxide. This, along with storing it in a dark, cool place, keeps decomposition to a minimal. You will inevitably lose some peroxide, but maybe on
the order of a couple percent a year with good storage. I have a bottle of 35% that I have stored for over a year and it has shown no noticeable
decrease in strength

I was wrong on the brand I buy, it's by Baquacil not HTH.

I got mine from the local hardware store. It is used to bleach wood. This particular kit has two bottles in it - one with a sodium hydroxide solution
and one with ~30% hydrogen peroxide. IIRC it was only a few dollars for each kit. It was called "Zinsser Wood Bleach Kit".

Over here in Canada, you can get 35% H2O2 from hydroponics stores.

Well I ended up buying some pool chemical by BioGuard called SoftSwim, has a big red circle on it with a white "C" in it. The MSDS lists only 27.5
hydrogen peroxide even though it says it nowhere on the bottle. It was sold for about $18/gal and came in a plastic bag (well a jug inside a bag).
Anyone heard of this or knows if it would work? If the MSDS only lists hydrogen peroxide does that mean that's the primary chemical or just the only
one considered hazardous?
Thanks

It should be fine. The MSDS only lists the chemicals deemed hazardous, but I think that the only other chemical in your peroxide may be a tiny amount
of phosphoric acid or some other stabilizer. This, however, should have no effect on whatever you plan to do with the peroxide

I can second this, in my experience the vast majority of hydroponics stores(the ones that 'subtly' market to cannabis growers especially) are a good
source for 35% H2O2. That being said, the 50% H2O2(and higher) products usually contain a good amount of impurities/stabilizing agents which make it
fairly useless for a lot of reactions.

I can get 50%H2O2 at like 7 dollars at my local chemistry distribuitor. If you can't find any, then what about using sodium percarbonate? it's a
source of very concentrated H2O2!! it shouldn't be really difficult to find!!

Also I would recommend going to ebay... http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1311.R...
