sulfuric

GrayGhost - 19-5-2015 at 14:25

In my country sulfuric acid acid is banned between other chemicals, is prepare with copper sulfate is OTC, of video Nurdrage, and work it.
I use anode of lead oxidate.

Nice.

Now to purify it so there is less crap in it.

Filtering is a good start.

Beginnings would be a better place for this.

Making H2SO4 from CuSO4 is not really what technochemistry is about.

The solution is blue initial, with hours become transparent i don´t know if contain Cu++ in solution.

I tempt concentrate in enamel vessel but in little sector with enamel the acid hot make it corrosion in bottom and all acid lost.:(

You got a mix of Copper ions, Lead ions and all sorts of crap in there.

Dump this thread and re-post in Beginnings.

You will (hopefully) get some Experts give you answers.

Edit:

Currently you are talking to the forum drunkard.

Im don´t drink Sr. I read your ut supra comment Sr.

More people will help you if you ask this in Beginnings.

Drunk you may be. But you got an awful lot more out of the OP than I was able to figure out.

If only I was half as competent on a good day as aga is on a bender.

Okay so maybe you should do some electrolysis with your blue solution, using copper electrodes. When there is no more brown precipitate, or the solution is clear, you can filter it and use it. Use a glass for the vessel, as the acid will corrode many other materials. If you are desperate, you can use some kind of plastics...

Effectively is a electrolysis ,cathode Cu and anode PbO2 ,to disappear
the blue colour, then evaporate water, vessel with enamel work fine, but my case are accidentaly.

My intention is share experience from point amateur.
Apparently I not wellcome in the forum.

Alright. So I wouldn't recommend using a lead anode, just use Copper. Lead is a tad toxic. There can still be a tinge of blue, as there always will be if you use two Copper electrodes. Filter out the mixture to get rid of crap, and now you can boil it down to get Sulfuric Acid.

Well, the video say use PbO2, carbon or platinum , but will experiment with Cu.

Thank Hawkguy

GrayGhost. Don't get the idea that you are unwelcome. You are very welcome on the boards.
It looks as though English is a second language and some of what you have written is unclear.

I make H2SO4 using the method you describe. I use a plastic container (PET). I use a copper cathode. I use a lead sheet for an anode. The anode gets a stable coating of PbO2 after a while and it does not erode.
I also have a good power supply that allows me to hold a steady current.

A typical batch uses 50g of CuSO4.5H2O dissolved in 200mL of water. I run it at half an amp for 24 hours. I then boil it down and get just over 10mL of concentrated H2SO4.
(I know I could do bigger and faster runs, but this is fairly convenient. The boiling down is the bit that takes time. The rest can be left unattended.)

Copper anode will not work. The copper will go into the solution and you will still have copper sulfate and not sulfuric acid.
Using a copper anode is a method for purifying copper and can be useful.

I have not had good success with carbon anodes -- they erode too quickly.
I do not have platinum.

You are welcome here !

What voltage are you using ?

Any more than 6v will make your liquid boil and bubble, and make the electrodes disappear.

Use a 5V PC power supply instead.

1) I speak spanish.

2)Was used supply PC 12 vc and 5v DC current.

3) Anode and cathode of Cu reduce Cu++ to Cu metal.

aga - 20-5-2015 at 07:47

Despues Bienvenido.

Hize tambien este experimento, y tenía lo mismo.

12V causa el liquido a hervir, y los electrodos se desintegran.

5 voltios estaba mucho mejor.

Donde vives ? No puede ser España, seguro, porque encuentré H2SO4 a la ferreteria.

Lo se venden como 'Desatascador' y es 98%.

Edit:

Viene contaminado con carbón.

Puede quitarlo con agua oxigenado (del supermercado), mezclarlo continuosamente, y con calor.

Al fin solo hay que hervirlo hasta veas humo denso, y esta 98% y claro.

Argentine, here two year ago all chemicals was OTC , today are banned by cooking drug:o

Ethanol is OTC , and Nitric acid.

Is tedious prepare chemical chips like Sulfuric, Hydrochloric acid, sodium hydroxide. Was sold other time in the hardward store ( ferreteria) and no cafeteria like say blogfast:D




aga - 20-5-2015 at 08:40

LOL.

Try the electrolysis again using 5 volts, some copper pipe and lead for the anode/cathode.

Use HDPE - i cut the bottom off a 5 Litre plastic milk bottle.

The Distance between the anode and cathode is important.

It will take a long time @ 5V but it will not boil or destroy your electrodes ni cajones.

Blogfast no say 'cafeteria', Blogfast say 'duroteria'!

El Sabe mucho pero sirve por nada.

Mejor olvidarle.

Sigues como digo yo.

Cuando el acido es hecho, robamos sus pantalones.
