Locating Nitric acid
So, as of this year there seems to be NO HNO3 left on the internet besides The Science Company, and industrial suppliers (excluding Sigma and other
companies that only sell to registered businesses). Since I'm not willing to have literally 200 gallons of HNO3 delivered to my doorstep, I'm really
looking for sources of 1-2L 65-70% HNO3. Besides The Science Company, I cant find anything else. Does anyone know of ANYWHERE on the internet or
otherwise that I can get it.
Thanks.

Grainger sells it, but it is outrageously expensive.

I'd like to avoid pricey items, too.

dudadiesel.com sells it, but it's not cheap there either. I always just got it by distilling from H2SO4 and nitrate salts, although now I can get it
locally from a jewelers' supply store in NYC.

It's actually not bad at all if you buy 10 liters, ($23/liter) since you're probably paying around $50 in hazmat fees no matter how much you buy at
once.

The only economical way to acquire nitric acid is to make it yourself. The hazmat fee is too high to make it worth buying.

In my experience, this is always true. The reagents required are not as dangerous, and much easier/cheaper to ship.

I wish that I could make it myself, but going off me previous experience with trying (keyword: try) to distill anhydrous perchloric acid (who knew so
many things are flammable), I'm sort of "iffy" with the practice. (No fancy grease, plastic clips, very limited budget, an "okay I guess" heating
mantle, and having easily available nitrate salts besides Ammonium being as plentiful as the Dodo...) It's probably more worth my time buying the
stuff and not wasting hours and hours of my life trying to make it, and likely failing.

Well it sounds like a better investment for you would be some nicer equipment. Buying a decent distillation kit and a couple kilos of potassium
nitrate on eBay would probably cost less than what you'd spend on purchasing nitric acid. And you'd be able to get a lot more out of it too.

If you have access to ammonium nitrate, you can react it with aqueous calcium hydroxide (EDIT: formed via reacting a soluble calcium salt and an
alkali hydroxide, calcium hydroxide precipitates out) to form calcium nitrate and ammonia gas. Vigorous stirring is required as calcium hydroxide
isn't very soluble in water and you want to keep the ammonia out to keep the equilibrium shifted to the right. Then if you have relatively pure
sulfuric acid, react the calcium nitrate with the acid stoichiometrically, and decant off the liquid, which should be relatively pure nitric. You
could even distill it for higher purity.

also, if you do not need anhydrous nitric acid then I suggest H2SO4 plus Ca(NO3)2
Calcium nitrate is often sold as a fertilizer,
the product Calcium Sulphate is not very soluble, so it can mostly be precipitated out by boiling the solution until you get close to the 68%
azeotropic concentration,
then, on cooling, most of the calcium sulphate will drop out of solution,
leaving (if you mixed the correct proportions / stoichiometric quantities) conc. nitric acid with some calcium sulphate as an impurity, about 0.5% if
my calculations are close.
(Plus whatever contaminants were in the original ingredients)
I have done similar, but not exactly this procedure, but others will hopefuly comment.

Its no longer economically feasible to purchase nitric acid for the amateur because of the limited number of suppliers, cost per ml of acid, and the
hazmat shipping. I would recommend that you purchase potassium nitrate from Lows (or a simular hardware store) in the form of stump remover. An
alternative to this is buying similar salts from ebay or other websites. A large amount of nitric acid can be prepared from drain opener, or sodium
bisulfate, and a nitrate salt by distillation.
Are their any limitations to members of this board manufacturing and selling nitric acid? Perhaps a local pick up could be arranged for members who
live in the same country/state/city? I imagine that the hazmat shipping is required by law.

I don't think that I live near anyone with Nitric acid, nor anyone who's willing to sell any. But, who knows. I hope I'll be pleasantly surprised.

Maybe what this hobby needs are community labs/better networking between members. I have been to many hacker spaces and I wonder if a similar concept
would work for amateur chemistry.

Somewhat. I have some experience with chemistry in hackerspaces, and I had a few problems with people dirtying up and breaking my glassware. I also
encountered way too many shady types who wanted to make drugs and weren't hearing what I was saying when I said no. I think it could work in the right
environment, but hacker culture isn't really it.

The hacker space I went to incorporated a RFID tag system to enter the workshop. Maybe that would help clean things up

Maybe, but how do you know that the person in charge of administering the RFID system isn't a criminal psychopath?

Is that like a thing, perhaps, that we should be worrying about? Is that common place?

I don't know how common that is, but not everyone who is attracted to something called a "hacker" space is the sort of individual you want left
unsupervised around your chemicals and equipment. That is the unfortunate reality of things.

Maybe it would require a special name such as Lab Space, Community Research Center, or Amateur Chemistry Lab Space

The other issue I've encountered, is that there are a lot more restrictions on chemistry labs than there are on other types of labs and hackerspaces
and such. Home labs can usually fly under the radar, as long as you're not bothering the neighbors with explosions or noxious gases, but zoning
restrictions and code compliance can make renting space prohibitive if there's going to be chemistry projects going on there. After remembering the
molten zinc sulfide and its associated scorch marks that used to be on the ceiling of my last place, I can't say I blame them...

So, what'd you do to to get the "ceiling art"? I "accidentally" made some ZnS one time. I was heating up some Zinc pennies on the stove to
melt them, and I think that the pot still had some leftover Sulfur from the plastic Sulfur experiment that I did earlier that day. It ended up
reacting with the molten Zinc, and detonated. It was much, MUCH louder than ANYTHING I've set off before. I legitimately thought that I'd blown out my
left eardrum. I really need to learn how to properly clean my stuff.

Wait until next year, in the UK sulphuric acid will be banned like nitric acid is. Amateur Chem in the UK is on the verge of extinction at this rate.
