Ummmm............ I'd like to see proof of that. It goes against logic and chemistry to say that a gas becomes more soluble in water as the temperature is raised. In fact, at a higher temperature the NH3 will be even more volatile and will leave the solution much easier. The only way to concentrate a solution of ammonia is to heat the solution to drive the NH3 out, and then collect that NH3 in a different vessel with a much smaller amount of water in it.
-
Yes, but there is NO OTHER WAY to remove the water since at room temperature NH3 is a gas. You have to cool it off pretty significantly, or compress it very well, in order for it to liquify.
-
Yes, but H2O2 is also an unstable compound that breaks down into oxygen gas and water gas. Whether it explodes or not depends on the concentration. When 3% H2O2 undergoes a rapid decomposition, it's not all too impressive. When 50% H2O2 undergoes a rapid decomposition, it's incredibly impressive.

Yup. Standard OSHA safety course demonstration at a University. They started a whole bunch of small chemical fires and showed how different types of fire extinguishers can only make it worse. The best method they showed was a huge pile of sand.

NH4OH IS NH3!! People just say NH4OH because they think that a base MUST have the OH ion someplace in it. In reality, NH4OH does not exist in a pure form. NH3 exists in a pure form, but NH4OH is simply the name for NH3 dissolved in water. It's used to distinguish between ammonia gas and a solution of ammonia. When mixed with iodine, the end result is the same. The 'big bang' still exists because the same compound is made whether you're using household ammonia (Without any additives or colorants/perfumes added to it), or you're using chem-lab ammonia. Actually, there is a slight difference between NH3 and NH4OH. When NH3 dissolves in water, it does slightly 'bind' to the water and temporarily forms the NH4OH compound. However, this isn't a very "stable" compound, so to speak, and will repeatedly dissociate into water and ammonia gas again. (That's why solutions of ammonia smell like ammonia. Because the gas is being given off).

Whenever I've made NI3 I've just used any old container and put the household ammonia (Which is a solution of ammonia gas in water, a.k.a. NH4OH) into the container and threw in some crushed up I2. I'd then throw in a few grains of KI to help the iodine dissolve, and let it sit for an hour or so while I'd go out and do something else. I would then pour out the solution through a coffee filter and let the 'muck' dry out FAR away from anything valuable or alive. I would also severely wash out the container with a ton of water and dispose of it someplace outside. (This way if there was any NI3 in there, the massive amount of water would dilute it so much that if it dried, there's wouldn't be a heckuva lot left to decompose).

I always find it kind of funny how over here in the USA, our country originated because we wanted separation from England. Yet, our system of measurements are all based on 'Old English' measurements defined by the King of England. So while England has smartly used the metric system, we're still using a system of measurements designed by the very people who our country didn't really like back in the beginning. lol.

NH4OH is kind of a misnomer. It's just another term for NH3 in water. (Techincally the ammonia does combine with the water to form NH4OH, but in reality it's just ammonia solvated by the water). I'm not even sure if anhydrous ammonia and iodine will give you NI3.
-
A similar reaction occurs with iodine and aluminum powder. But the gas given off is incredibly corrosive, yet beautifully violet.

Well, the LD50 is a good quantitative benchmark for the toxicity of a substance.

Oh yeah. It was designed to be a potent cough supressant (which it is) without the addicting effects of morphine. It was called 'Heroin' because it was chique to call things after ladies, and because they thought it would be the hero of the times. (As in allowing people to avoid the horrendous coughs, but not be addicted). Ummm....... OOPS! This was all before the FDA and other testing agencies were founded. So they only had the tests that the doctors did on themselves and people they knew. There was no long term testing to see that people would become severely addicted to it physically, much more so than morphine. It's one of those drugs that had real good intentions behind its synthesis, but horrendous results.
-
While not really the most 'lethal' in terms of one dose, over a longer time diacetyl morphine is perhaps the most hideous and horrendous of all 'designer' organic compounds.

Here ya go. Now you can get some of it.

Check out my collection of DVDs. Pretty much anything on there is good. (That's why it's in my collection. )

Ummm............ I got my 20-25 gram sample of barium metal for only about 30 bucks. If you paid $100 for a few grams, you were SEVERELY ripped off.

Exactly. It's like asking what the 'strongest' acid is. There are so many different ways to define 'strongest' that there really is no answer. For your question, HCN, H2S, HF, Cl2, F2, Br2, As, Hg, dimethyl mercury, dioxin, benzene, etc. etc. are all things I wouldn't want to have in my body. There really is no way to define what the 'strongest' or 'most dangerous' is.

CH3COOH is acetic acid. What you need to do is convert the mass into moles to get molarity, and use the Ka equation for acetic acid. (Ka = ([H+][CH3COO-])/[CH3COOH]). With that equation you then figure out the concentrations using the Ka value and the I.C.E. table. (Concentrations at Initial, change in Conc., and Concentrations at Equllibrium). You shouldn't have too much trouble with this one.

I found out the hard way that the Habanero Pepper Plant grows like wildfire if given a chance. I had a few seeds that I planted a few years ago, and I must have ten or tweleve pounds of peppers from those three plants. I will never be able to go through all of them cuz they're so damned hot, but at least I have 'em if I need 'em. I still cannot get over how those 'tropical' plants grew so crazy here in New England.

Heh. Pretty funny.

I thought that was plutonium? (Only heard about the real thing, not the movie).

There should be a 'suspected' carcinogen. It hasn't been conclusively proven. In fact, the human body requires a moderate amount of the chromium ion in order to help metabolise sugars. So I wouldn't go eating it by the barrel full, but there is absolutely no need to get yourself into a hazmat suit just to work with some Cr ions.

I fully support stem-cell research. I am a Type 1 (IDDM) Diabetic and my ONLY hope for a cure is to figure out how to regenerate the islet-beta cells in my pancreas through stem-cell research. It sickens me when I hear protesters, and people who don't even know me, say that I should not be allowed to get a cure.
