Making hydrochloric acid

jsatan · September 12, 2005

Hi, YT this is aimed you really,

how do you make your hydrochloric acid?

I've been thinking about how to make it.

I thought of a fun way.

make 2 electrolysis cells.

one has salt in it (table salt)

the other just water

Build some tubing etc and mix them just b4 burning.

this should make water and HCl.

I've burned Hydogen oxygen mix in a homemade burner, which heated the burner to a nice white (very very bright).

So I've got no troubles there.

I take it there has to be a much better why then burning them?

Well anyway I could make hydrogen and Cl in a better way Al/Na(OH) mix and bleach/acid mix.

Any ideas. chems are limited as I've not got around to buying alot of them, but I've got some.

NaCl + NaHSO₄ ---> HCl + Na₂SO₄

Heat the reactants and collect the HCl(g) in a syringe and then dissolve it in water to get hydrochloric acid.

I remember reading this, but I also heard YT say its a lie, so I just crossed it off my list as I only read it in one place.

So its table

salt and vinegar -------> HCL and sodium acetate.

I was thinking there sould be a easy way to remove the sodium acetate.

Thanks,

PS ignore that poop.

jumped the gun

Whats NaHSO4?

latentheat · September 12, 2005

Whats NaHSO4?

Sodium bisulfate, sold at every pool supply place as solid pH down chemical. It's basically partially neutralized sulfuric acid.

YT2095 · September 12, 2005

I make mine with common house salt NaCl and Sulphuric acid (70%).

I then distill that mix into a another vessel containing a small amount of ice water and held in freezing mix.

it`s important to use all glass apparatus (HCl rots organic matter), keep the area well ventilated too.

I make Nitric acid the same way (I use Sodium Nitrate instead of NaCl), I don`t use Ice water in the receiver vessel either.

that`s basicly it

jsatan · September 12, 2005

aha, Hummm. I've not got any of thos,e No sulphuric acid with out buying it.

Would my idea work?

I've got a platinum plate thats is used for hydrogen fuel cell.

could this be used rather then burning it?

A quite useful link for manufacturing HCl.

Neither too long nor boring. Have a look at the pdf when you are interested.

I don't make my HCl :rolleyes: you can buy it almost everywhere in any hardware store and it is dirt cheap.

burning hydrogen in a chlorine gas oxidiser will make HCl gas, that could then be dissolved in water, but it`s alot of messing about and as well as being dangerous. I`m not sure what sort of yield you`ll get from it, the flame will be quite hot, as will the "Exhaust gasses" (HCl), how you plan on "Trapping" that and them bubbling it through water is a project I`de rather watch from a distance

jsatan · September 13, 2005

I've done it before with hydrogen and pure oxygen,

I built my self a micro burner.

The flame that was just hydrogen with the valve fully open was about 2inch max.

Nice and pointy, .

I would then let the O2 in (very very slowly) and then it would get smaller and hotter until it was so small that It was just a white dot (very very white).

But I wouldnt say there was more heat coming out of it than a normla lighter on high.

I'll thyiknk about it,

YT2095 · September 13, 2005

be extremely carefull it doesn`t or can`t "back up" into the mixer, it`ll explode!

Chlorine gas will "attack" many metals also (unlike oxygen that often leaves a protective oxide layer).

isn`t there anyway you can try this remotely 1`st?

jsatan · September 13, 2005

lol. the mixer is about 0.5cm long so it only mixes just before being burned.

Nah I'm not going to mix them b4, that would be stupid and crasy.

It has 2 pipes coming in facing each other which mix it well. then it T's off to the burner.

H2 and O2 can also be kept as a mixture and be relatively stable. If you have pure H2 and pure Cl2 mixed together, UV light (a.k.a. sunlight) will overcome the activation energy barrier and cause it to violently start reacting. (It's actually kind of neat to see).

I said I've not mixed either H and O nor H and cl,

Grrr

Yeah using a camera flash would work,

a little Factoid complements of my data book:

Oxy-Hydrogen burner temp: 3073K

Oxy-Acetylene burner temp: 3773k

just thought you might be interested

Cool. well nit and hot.

You havent got H and Cl in there have you?

Is this a real book or an online thingy?

(I'd like to read)

I used a heat putty that sets rock hard to cast the burner nozzle.

I used a thin wire and built around that, then pulled the wire out.

When it was burning at a small point it started to cook the putty but very slow.

lol. so much fun,

jsatan · September 13, 2005

Just thinking. Maybe if I was just just push the gases through water (bubbling) and have a metal halide shinning on them.

I'm not sure if that would make the right about of UV light.

If it was slow and the bubbles kept small it should be too bad.

I know this going a long way around things, but its just and idea.

I don`t have anything for H and Cl.

Yes it`s a REAL book (I just love the old Fashioned "Retro-Tech" sometimes) )

i got a whole lt of sodium bi sulfate just so i could make hcl with nacl. havent gotten about to doing it ye tho

jsatan · September 16, 2005

I've just been watching telly.

And I've found out how/why I got a very bright light from my hydrogen oxygen burning.

In the old days they used to heat lime this way to make white light.

Thats what happened with my burner,

Even history finds it way in...

(the term lime light)

Me too! You can buy HCl at any hardware store under the name Muriatic Acid (it's used to clean certain tiles). :cool: When buying it I would advise you to destilate it, just to be sure it doesn't have any impurities!

Alchemist · September 18, 2005

If you really want to make it then you could:

2NaCl + H2SO4 -> Na2SO4 + 2HCl

NaCl + H2SO4 -> NaHSO4 + HCl

If you don't have sulfuric acid you can use conc. phosporic acid!

NaCl + H3PO4 -> NaH2PO4 + HCl

2NaCl + H3PO4 -> Na2HPO4 + 2HCl

3NaCl + H3PO4 -> Na3PO4 + 3HCl

and i dont really recommend do it too
