Hydrogen peroxide concentration
Hydrogen peroxide concentration
Can anybody please tell how to calculate molar concentration of hydrogen peroxide from % concentration? for example if we have 6% hydrogen peroxide what is the molar concentration of the same? Thanks- NEHAL

Re: Hydrogen peroxide concentration
this might be over simplified but this is how my brain works around this.
6% = 6g in 100ml
that means 60g in 1000ml (1L)
known amount / MW = M
so 60g / 34 = 1.7 M
i think that is right - i am sure soem one will correct me if i am wrong![Smile :)](./images/smilies/icon_smile.gif)

Re: Hydrogen peroxide concentration
Hi Nehal,
I agree with Annette's calculations for 100 vol peroxide. I have attached a table I made some time ago when we were supplied 120 vol or 100 vol, depending on what the supplier sent. Hope this helps.

Re: Hydrogen peroxide concentration
thanks for that
and for the table good for quick look up and no thinking (shameful of me i guess but ths time of year no extra thinking is a good thing)

this is fantastic concentration calculator it is free to use (limited to few chemicals), select % and it will calculate molarities![Applause =D>](./images/smilies/eusa_clap.gif)

Re: Hydrogen peroxide concentration
The concentration of Hydrogen peroxide can only be determined by its reaction rate as it is unstable and wants to revert to water, therefore I always store in the fridge

Re: Hydrogen peroxide concentration
Does anyone have a copy of Franco's table above? I can't open it for some reason... (it's possibly too old a version?)

Re: Hydrogen peroxide concentration
This is the best thing I've seen for ages. Thank you. I now have a copy with the H2O2 and in the recipe book.
