H2O2 Quick Question
Hi Group. Just a quick question today. I found that a local store sells 27% Pool and Spa grade hydrogen peroxide for $17/gal. However, it is called
"Stabilized Hydrogen Peroxide". Does this affect its ability to oxidize compounds such as hexamine or acetone, among others? In addition, does this
"stabilization package" have any affect on its use in general chemistry for other hydrogen peroxide applications?
Thanks!

No. For most uses, this is perfect.

That is what I thought. Thank you so much, Adas!
As a side note, does anyone out there know what these "stabilizers" are and why they are even in the product? Is it contaminated, the same way
denatured ethanol alcohol is, so you can't use it as "food grade", and are forced to have to pay a higher price for the food grade variety (which is
usually about 35%)?
I tried reading up on the stabilizers and there was no explanation I could find out there in Googleland.

Phenol, tin, colloidal stannate, organophosphonates, acetanilide and nitrate have all been used as H2O2 stabilisers!

That is quite a variety of material they use! But really, what does it stabilize? The material will still turn your skin white and it will still
oxidize metals and other chemicals, "stabilized" or not.

Peroxide slowly decomposes over time,releasing oxygen and leaving you with water. Stabilizers slow or prevent(?) this process in the case of H2O2.
Refrigerating your peroxide is another way of slowing the decomposition, I need to store my food grade variety like this as it contains no
stabilizers. I must say though that my small bottle I keep out of the fridge for use never pressurizes and does not seem to have lost a noticeable
amount of concentration in the last 6 months, I haven't titrated it in a long time though.

Makes sense. If I bought this material, I was planning on keeping it in the fridge, anyway. There are warnings against freezing it. I am not sure
why, but it is not recommended.
Thanks,
Joel

My H2O2 is stabilized with benzoic acid and tetrapotassium diphosphate.

Freezing it is one way to further concentrate the H2O2, although, it does not work very well, at least in my experience.

As for the stabilizers,
I saw a bottle of H2O2 3% at a pharmacy (Walmart) that says non-medical ingredients, stabilizer, sodium phosphate (perhaps Na3PO4), sodium stannate
(not sure which one).
