I imagine any half-decent parent would immediately forbid any child to mill gunpowder ANYWHERE, let alone indoors.

vishal, welcome to the forum. I'd like to point out a couple of things: 1) the last reply to this thread was 6 months ago, so anyone who wanted a reply has probably either given up or gone somewhere else or got their answer. 2) there are many ways to make cupric chloride, and most of them have been discussed in this thread already.

you could ask someone who can buy things on the internet. it's very cheap. Or anyone who had some would be likely to give you some, since it's so cheap.

OK what you need to do is google "reaction of dichromate and ethanol". You'll be able to find a balanced equation which might explain things better. After that, all you have to do is realise this a volumetric analysis. Volumetric analysis questions usually follow the form of a c=n/v calculation, followed by a stoichiometry calculation, followed by another c=n/v.

try looking up the individual reactants ("lampblack", "alum" etc) to find out their real chemical names or major components. then you might be able to google to find the reactions they undergo

the fact is that i'm not sure. A modern procedure would mention the hazards. Also, it'd probably mention the reactions involved which would give more clues as to the safety or lack thereof

I wouldnt advise trying to reproduce an experiment which appears to be several hundred years unless you can find a description a little less outdated. or at least a translation into modern english. I'm not sure about some of the words there and I am sure that in the days when this experiment was described, safety and harzard reduction wasn't part of the game, which is why so many experimenters blow their own faces off in those days.

OK if cold fusion existed on a useable scale, someone would be using it. It would probably have been sold to someone and be used to create weaponry or large power stations in a country desperate enough to try. So, if cold fusion was viable, we'd surely know about it. we don't, so it probably doesnt.

I have 17 bottles of pure bromine in my lab. I try not to touch them.

does a battery even weigh 21 lbs? it seems a lot to me. perhaps i am seriously underestimating car batteries

you've got to know, if nitric says he doesn't recommend it, it's got to be unsafe.

paraguay??? what r u on about? either way it doesnt seem very efficient. maybe ten bullets... even then it's still not much

i often use gaseous chlorine... i guess that'd pretty bad too... got a lungful of it last year... yuck... oh my god it hurt too

you wont get much lead from a car battery. i figure you couldnt make a single bullet from a battery. It'd take a lot of effort for very little return. Also of course i don't need to remind you of the dangers of the sulphuric acid etc etc

not mistaken. Psilocybe is the most commonly used but some of the harder druggies like to poison themselves with amanita so they get wilder visions. Anyway i'm not sure of any chemical methods to isolate the muscaria. Generally the very active substances in mushrooms tend to be very sensitive too, so destroy one, destroy them all.

ive used Mn2O7 too, but such small quantities it doesnt worry me. The most hazardous situation i remember being in was when i used 125mL at a time of TiCl4. Our laboratory used plastic syringes which would slowly dissolve while you transferred the corrosive liquid.

What's your purpose? are you trying to extract hallucinogens? If so, please try a different forum. the shroomery.org, for instance.

vedmecum, The question was: Dissociation of the H-H bond to give H+ and H- would be a different question. Please only answer questions if you really understand the question. You are confusing other members.

vedmecum, i think that aaronaldo is saying he wants to find the percentage yield based on an actual yield he has either got or been given.

i'm sure ive used DMSO as a solvent and had smell issues. perhaps the two weren't related though...

I think DMSO would be a really bad idea. it smells AWFUL. I think it's also fairly hazardous.

please dont post the same thread twice. This thread has been answered in the chemistry forums. If you want people to answer your questions, show them some courtesy by not doing this again.

absolutely. it wasn't meant as any kind of criticism, just a reminder to the poster to try and stay on topic.

ecap, thanks for your enormous post. I would like to point out, however, that the question was already answered, and that your post didn't contain any of the information requested by the original post :0)

how about sciencedirect? you could also try searching for "adsorbtion of latex" and seeing whether any of the results are interesting... it might be that latex is easily adsorbed on surfaces which containa functional group which you can then incorporate into your SAMs
