As someone has mentioned the Rooto drain cleaner is of about 96% purity(substantiated by thehomescientist and in my own personal titration) and is at least as pure as the acid you make and most likely far greater.
which temperature you use on the plate for heating out the hydrogen peroxyde in 1:38?are you sure than all the hydrogen peroxide will came off from the sulfuric acid after heating?
the first 10 drops taked out in 0:41 are about 100% pure hydrogen peroxyde?
Nice! I added 10 mL of 30% hydrogen peroxide, pulling the contaminants immediately out and generating an impressive amount of heat/bubbles. I have a clear solution of what I believe is sulfuric acid and am contemplating if it's usable yet. :P
Also, get "Rooto Professional Drain Opener" from Ace Hardware instead of a contaminated acid. It's quite cheap, very accessible, and light yellow instead of dark brown. :P

@hustal69 nope. unlike with hydrogen peroxide and water, the hydrogen bonds between HCl and water are quite strong, to the effect that a solution of HCl and water will no longer retain the respective properties of each component (i.e., you can't expect the water to freeze out of an HCl solution).
@hustal69 purify, yes; look in the suggestions bar to the right and youll find a video by TheHomeScientist on purifying hydrochloric acid. concentrating it, however, is a much more difficult matter.
Hi, The drain cleaner that you buy at the hardware stores is sulfuric acid with inhibitor added to it, the inhibitor is mostly phosphoric acid as far as I know (also called Rodine ). Is that what you used for this experiment ? I am trying to remove this Rodine from it because it totally mess up the experiments as it prevent the acid from reacting to metals. Any idea? thanks
@simpledate as far as i know, the sulfuric acid that i buy and use does not contain phosphoric acid. are you sure you are buying the concentrated variety; typically, sulfuric acid drain cleaners that are less concentrated (they usually come in overly colorful containers) will contain large amounts of buffers and inhibitors. if you are certain that your acid is the concentrated variety, i suppose could heat it as phosphoric acid decomposes at ~150 degrees celsius.
@simpledate Not sure if I understood clearly ur comment. But Rodine isn't phosphoric acid. In essence, these are products that are used to permit corrosion protection to metals from strong and corrosive mineral acids like phosphoric acid, HCl, H2SO4, etc. U don't inhibit an acid with the same acid or even another one, it don't make sense.
hopefully someone knows an answer for me i make copper sulfate and zinc sulfate by making a weak solution of sulfuric acid by mixing sodium bisulfate into distilled water until no more disolves after these experiments i wanted stronger sulfuric acid so i made my sodium bisulfate and boiled it down and set it aside well i wanted it stronger so i boiled way down to almost no liquid left and i let it cool when i checked back on it it had crystallized into really sharp crystals what are the crystals
@HUsoldier171 do you mean "purify"? my process doesn't concentrate the acid; it just clarifies it. to concentrate sulfuric acid, you can heat it to drive off water
@jeremiahswee so how could i get like 98% sulphuric acid or higher i already have 96% acid it is a drain cleaner which is already clear so i don't have to purify it
@yodarox89 you can use vacuum distillation to concentrate it to about 80-90% however if you don't have a setup (which you probabily don't) the boiling method can concentrate it to around 50% a controled evaporation that is, keeping temperature at around 60-70 degrees celsius, with this way you can keep yor original yield as well, not just get a few drops
I had been wondering if peroxide could be distilled by boiling it but I wasn't sure since some chemicals can release some pretty dangerous fumes......THANK AGAIN!!!!
@yodarox89 if you boil it over 80 degrees celsuis the peroxide will decompose into hydrogen and oxygen (which is an explosive combination) but to much water and other things are with it and with such little peroxide it simply wont explode on you no matter what you do, i've boiled it with an open flame many times inside the house and it wont do anything

@jeremiahswee is that procedure in the step one suitable to get concentrated hydrochloric acid/muriatic acid aka HCL?
I CAN SEE THE MELTING POINT OF HCL IS: -25 C
that's the datasheet if u can check please:

@jeremiahswee how long would i have to boil it to get it to 30% if i start with 300 to 500 ml
HUsoldier171 8 months ago
@jeremiahswee so could make fumming acid from 96% sulphuric acid by boiling off like 5%
crapbag1997 7 months ago
@crapbag1997 no. sulfuric acid reaches an azeotropic concentration of ~98.3%. at this point, it cannot be further concentrated.
jeremiahswee 7 months ago
@jeremiahswee so how could i get like 98% sulphuric acid or higher i already have 96% acid it is a drain cleaner which is already clear so i don't have to purify it
crapbag1997 7 months ago
@crapbag1997 you already have 96% sulfuric acid? that's about as concentrated as youre going to get.
btw, are you trying to make fuming sulfuric acid? i wouldn't count on it.

i do not believe this, however i shall try it, haha, you know, freezing peroxide is not the best way of concentrating it
TheHappyShack 1 year ago
@TheHappyShack it isn't?
please then.....I have been trying to refine peroxide for quite a while, however only with the freezing method.
is there a better way? do you know of it? How do i do it?
