Iodine preparation for who needs it
Iodine has been added to the DEA list and may be hard to get a hold of. If you need iodine and would like to "make" it, here's a set of reactions that
you can follow to prepare yourself a solution of iodine.

This is just asking for the DEA to ban KI too. Soon we may all have to resort to the destructive distillation of copious amounts of kelp.

Interestingly, the procedure is taken from Illustrated Guide to Home Chemistry Experiments: All Lab, No Lecture by Robert Thompson, who was
asking for help here some time ago.

I have a problem here with this author's method. He uses hydrochloric acid as an acidulant for the iodide oxidiation. Sulfuric acid works MUCH better
because sulfate DECREASES iodines solubility in water. In fact when I do it the filtrate is almost clear!
I realize that he trying to use readily available chemicals, but if you can get potassium iodide, you can certainly get battery electrolyte sulfuric
acid.
@kilowatt-Do you think any DEA agent is clever enough to watch the video? LOL But seriously how many chemicals can they restrict before people get fed
up anyways?

Picric-A: I'm sure if you could find SciMad or RogueSci from a simple google search, those meth cooks can find how where to get what they need.
Kilowatt: I really don't think the DEA will restrict something that is vital to someone's safety near radiation. If you aren't near a nuclear plant, a
hospital's pharmacy works just as well as I found a whole shelf selling potassium iodide.

A joke as well, I'm sure. My prediction is that they will restrict KI except for in pills/extremely dilute solution. Have you ever tried to extract
a usable amount of KI from "radiation pills"? I haven't. Mostly because there's (this is just a guess) a few hundred mgs per pill (probably less).
Never underestimate the ability of an oppressive government to restrict something in the name of safety that actually does exactly the opposite.
I suppose a good paraphrase would be: don't underestimate the US govts ability to do whatever the hell they want and get full support from sheeple.
EDIT
I'm sorry guys. I didn't realize until now that this was under reagents aquisition instead of legal/societal issues. Feel free to delete this if you
deem necessary.

I dunno, the city of New York wanted to ban geiger counters. And you'd think if
people were ever going to get fed up with restrictions on chemicals, iodine tincture would have been the straw that broke the camel's back. That
stuff was a pretty popular antiseptic. If that didn't do it you'd think ephedrine/pseudophedrine would have for sure. I know plenty of people with
allergies that are seriously hurt and outraged by that one. The fact of the matter is, it doesn't matter how fed up any citizens are, the government
will keep banning more stuff cause no one's gonna stop them. If they can
restrict other medications so heavily why not KI?

Where I live in Western Europe chemicals do not seem to be unreasonably restricted.
Obviously if you buy safrole or large amounts of 30% hydrogen peroxide you may start to draw unwanted attention to yourself.
But I would argue that hobby chemists should not be trying to make MDMA or large amounts of explosive materials anyway.

That is true though. I believe the US can and will restrict anything they seem fit for destroying anything. There should be a "progress" report on how
the US govt. is restring and a graph to determine when all of our rights will be lost.
Anyhow, a little off topic, I apologize. Have fun with the video, I hope some of you will like it.

I had the impression that sulfuric acid, since it's an oxidizer itself, led to unwanted side products (sulfur in the iodine, or H2S in the air).

Sulphuric acid does not lead to unwanted side products if it is dilute. Only concentrated acid will produce other side products.
@ScienceSquirrel: Right now, you still can buy almost every chemical in the EU, but I'm afraid that will not be for long anymore. A lot of new laws
are in preparation, and if these laws are implemented, then the situation in the EU will be much worse than the situation in the US.
- no oxidizers may be sold to the general public
- no strong mineral acids of decent concentration
- no compounds which are marked as T, T+ or Xn (combined with some R-sentences)
So, even stuff like nickel-salts, cobalt-salts and chromium-salts then will be prohibited.
There is another thread about this subject, so no need to respond here.

i dont think laws like that will pass...
i mean anyone with a swimming pool (or not as the case may be...) can order swimming pool chems, eg. calcium hypochlorite, hydrogen peroxide, sodium
bromide ect... and these can be used to make things like sodium chlorate ( Calcium chlorate + sdoium chloride--> sodium chlrate + calcium chloride)
people will find ways of replacing the chemicals that can no longer be purchased.

Strong hydrogen peroxide is becoming tightly controlled in Canada, no more swimming pool use and users of the concentrations over 3% will be
regulated, registers, and must provide tracking data. From what Len has said iodine and iodides are under similar tight controls in Australia,
possession of them has legal implications.
This leads to either products containing only a small amount of the chemical, 3% H2O2 or aquarium iodine sources at a few grams per liter, or in
mixtures that are much less useful than the pure compound - pool and cleaning chemicals.
In the ceramics field there is a push towards frits for colouring, glasses including the elements that once would be added in the form of simple
compounds. Like coloured glass for art use, manufactured by a small number of companies that are easily monitored, and the dilute solution of the
element in the glass is hardly a convenient or economical source.

I think not_important is right. Pure chemicals will disappear and so-called convenience products will replace them. So, no pure HCl of decent
concentration, but some concrete cleaner with lots of other stuff added, I also have seen the coloring powder for ceramics in all colors people want.
So, a ceramics hobbyist does not need pure nickel salts etc., but only the coloring powders. For chemistry purposes this is absolutely fatal.

A lot of the reasons for pure consumer chemicals going away is probably business/economics rather than paranoia/fear of chemistry/etc.
Pure-ish compounds are low margin commodities, so it is hard to make a lot of money selling them. OTOH, make some branded cleaner or whatever, that
has a similar role to a chemical compound, and it is higher margin, and more differentiated from competing products (at least on the surface).

Well, couldn't basic acids be made such as hydrogen chloride through electrolysis of a saturated sodium chloride solution and dissolved into water?
The lead chamber process or haber-bosch process. If it comes down to that, I'm sure that some people who really find a need for it will come across
some materials or a group of local who believe in the same thing. Then a simple plant creating each chemical could be underground.
I highly doubt that even though the govt. restricts access to chemicals, that it will stop home chemists. I'm saying that if things do become more
restricted, people will improvise (like we do today, just on a more "harsh" scale) or go into underground development to create and distribute those
chemicals. I think things can only get harder but will never stop.
If pro is the opposite of con, shouldn\'t Congress be the opposite of progress?

I think alot of a future "underground" movement but this would be extremely difficult to implement for a number of reasons:
1) The number of hard core home chemist is VERY small and spread out over the globe( as seen in this forum). . With state sponsored education this is
by design of coarse.
2) The authorities have total free access to all communication venues and this makes communication almost impossible for would be underground agents.
3) With further restrictions, less chemical availability would make home chemistry not really worth the effort and the numbers of home chemist will
decrease further.
4) Many home chemist have families, careers, futures and other responsibilites and may not be willing to deal with the increased risk of such a hobby.
The best solution as offered by other memebers here is simply relocate to the third world. This is especially an attractive options considering that
you will be living in a better climate and be eating healthier food unless the third world country you are considering is totally starving or under
strict dictatorship.

I can see the restrictions and the disappearance of basic reagents from the consumer market largely taking home chemistry a step back, making
everything slower and more tedious, rather than putting an end to it. For example instead of doing an experiment or reaction that uses sulfuric acid,
home chemists of the future will need to make their own sulfuric acid starting from very rudimentary and inconspicuous materials like gypsum and
charcoal (even garden sulfur will be unlikely to exist as it does today, being replaced with some proprietary fertilizer blend). Such a thing is
quite a project in itself and I can see it driving many, but not all, home chemists away.
Back on the subject of iodine, home chemists of the future will likely be forced to turn to either black market sources, or natural sources, since ALL
iodine compounds are likely to become highly restricted and unobtainable to common folk. For example several tons of dried kelp could be burned in a
closed furnace and the smoke condensed and processed to obtain several kilograms of iodine.
With the decreased demand by private individuals, I can see glassware becoming extremely scarce too, if not flat out illegal as it already is in
Texas. Home chemists will have to become glass blowers, and this in itself may become more challenging as fuel and oxygen cylinders for torches may
become more regulated as well.
During the dark ages, science and chemistry (alchemy) was highly restricted and punishable by death as heresy, unless you happened to be the king's
personal alchemist (state sponsored). Yet many private alchemists continued their pursuits despite the risk, obtaining reagents from natural sources
or underground trade. This is not too unlike the situation we are heading toward with chemistry now.

Well, and not to mention the news I was reading about Iran planning to detonate a nuclear bomb miles ABOVE the US to generate a giant EMP pulse
taking us back to the bygone days of the early 19th century. It is plausible something like this could happen although I wonder if this is
propanganda to strike more fear in us for the sake of the "war on terra"
I doubt EVERY iodine compound will be regulated. I am sure there is something we can oxidize to obtain iodine. I mean iodine is an antiseptic Well
will see for sure in the future.

This is actually not plausible. A bomb small enough to fit on an Iranian vehicle, launched to a height achievable by an Iranian vehicle, wouldn't
make enough of a pulse to "take out" more than a city. "Taking out" the entire US would take an enormous bomb, detonated at orbital altitudes,
neither of which are really within Iranian reach.
EMP is bad, but the fearmongers are <i>vastly</i> exaggerating the risk.

Not a very good way to get iodine. Dried kelps are charred by incomplete burning at the lowest possible temperature, and the ashes worked up
for their iodide content. There is also a purely wet process that does not heat the kelp at all.
You need to have the proper types of seaweeds, others have a much lower iodine content. Note that some districts prohibit unlicensed harvesting of
seaweeds, to prevent damage to the littoral zone and associate life.

I believe that in places such regulation and banning has already been done. Perhaps an Australian member could comment.
Simple tracking, requiring every purchase of iodine-based antiseptics, could keep yearly purchases below a couple of grams per household. The US has
done this with pseudoephedrine, tracking sales of that with such humorous results as drug rids on families where several family members independently
restocked the household supply on the same day - thereby exceeding the monthly limit.
