Picture of Fun With Acid!
I'll show you something neat you can do with some easy to obtain acid.

Step 1: Supplies

Picture of Supplies
You'll need the following:

- Muriatic acid (hydrochloric acid)
You can find this at your local hardware or paint store.

- Small glass

- Some shiny pennies
Only pennies from 1982 and newer will work.

Why shouldn't you put water in acid? That should just dilute it. Also would an aqueous solution of hydrochloric acid work?
The reason to add acid to water is that many acids boil at low(ish) temperatures and heat up when combined with water. If you add acid to the water, you end up diluting the acid out very quickly, raising its boiling temperature closer to that of the water. Hot water with a little bit of acid in it is no big deal. If you add water to acid, the first few drops of water mix up and create heat in a very concentrated acid mixture. This can boil or fume or worse. Hot acid with a little bit of water in it is a problem.
HCl(hydrogen-chloride) is not a liquid, it's a gas, hidrochloric acid can be mixed safely with water since it's the solution of HCl, but do not try this with sulfuric acid, because the water boils because of the exothermal reaction and the acid can go out of the container. If you want thin sulfuric acid you need to mix aysmall amount (few drops) of sulfuric acid with much water, because the water absorbs the heat of the reaction.

Certainly, adding hydrochloric acid to water is far less dramatic. Still I notice a significant rise in temperature by adding 30+% into water. If that water is already 90 Celsius then you could get a POOF of HCl vapors in your face from the exothermic dilution.

Adding water to HCl is an exothermic reaction. If you add water to the acid there's a chance that it will splash up and get you on the skin or in your eyes. You always slowly add the acid to water. Not water into acid.

Yes, you're right. Concentrated sulphuric is quite exothermic, you need a bit of stirring even if you are doing it in the right way L (Hydrogen-bonding)

When i readed : Fun With Acid! , i was really hoping it would be an instructable about our good friend , Lycergic Acid Diethylamide :p Nice Instructable anyhow
what is 'Lycergic Acid Diethylamide'?
lysergic acid diethylamide also known as LSD, is among many hallucinagens. LSD was created by albert hoffman. look it up on wikipedia, it'll tell you all about it.
lol, 'daddy, that funny chemical made me see things'......
I've seen things! I've seen them with my eyes! I've seen things, they're often in disguise!

a powerful hallucinogenic substance. (also known as, "gettin' high, dude")
I love that friend.

does it wok with old muratic acid because ive had some in my garage for about 3 years and also how can you trick someone if the dime dosent have the other side of the penny

"Don't breath the fumes" No problem breathing the fumes - they're competely non-toxic. They do, however, go bang - It's hydrogen. Leave an inverted tub over the penny to collect the bubbles, you can celebrate getting your (quite excellent) penny shell by lighting the hydrogen!
I depends on the molarity of the acid, HCl produces Chlorine gas naturally, which is one of the most notorious killing devices known to man.
Not when reacting with metals: HCl + metal -> metal halide (salt) + hydrogen gas.
Yes, but any unreacted HCl will still put out chlorine gas, and since these are amateur chemists they probably won't balance the moles, and while he gives measurements, not everyone will follow these.
Kiteman, I thinks thats the first time you've had fun on 'Ibles...
Fine, fine, but the first time having fun with chemistry, and not the social kind. Plus, I haven't been on ibles for about 4 months...

After the first smell you will consider berathing it again because the hydrogen-chloride goes out of the heated solution, and it is irritating.

I was referring to the fumes of the muriatic acid, actually. Those are quite noxious.

Put it in a plastice 20oz coke bottle (1/4 way full) add a couple foil balls and close it up..... mustard gas bomb.... and you all say you cant have fun with acid!!!
That's not mustard gas! Do NOT try to make mustard gas becasue that's NEUROtoxic(it affects your brain). With this bomb the sound of the exploding hydrogen or your hurting lungs will affect your brain not the gas...
A) What you described is a felony to detonate in public areas. B) Neurotoxins arent something many people can make in their backyard.

how can you have fun with acid? It burns....
how can you NOT have fun with acid? IT BURNS!!!!! cheers, (and safety) mspark400
yah,your right.I have GOT to try it on my bros...... mwahahaha....
I've gotten it on my skin before, it itches.
Oh ok man did it burn?
Stung a little bit, felt like touching a stinging nettle plant. I only got burned because I was stupid enough to forget about washing it off.
