  1. You will know when it reaches 70% because at that point, when it decomposes, all of the water in it will be vaporized, leaving little or no material left.
  2. If you are seriously incapable of evaporating water, you really shouldn't be dealing with things that explode. You know, when you blow on something to make it dry faster... evaporation's like that, except you don't do anything at all.
  3. Silver also catalyzes the decomposition. It's often more convenient that manganese dioxide, especially if it reacts with the zinc when you try to get it out of the battery...
  4. I don't exactly trust myself not to cause an explosion, so please tell me, could this reaction work with vapor distillation? And would it use the same setup as regular distillation?
  5. Well, the good old brine solution will do just that... So if saltwater counts as from scratch, then that's all you really need to know! There's also a way to make lye from birch ash, limestone and water, but you probably want electrolysis... Then again, there is a search forum button...
  6. Ah-hah! Well that also means I purified the sulphuric acid, sort of. Well, what are other dehydrating agents for ethanol? All the sources I've seen say that there are others, but they won't tell me which. Any searches I do for that sort of thing returns all sorts of funky patents, but nothing useful! If you are heating it over 120C, what keeps the ether from exploding?
  7. And just think... In the late 19th century, people used to drink that stuff! Going out for a smoke, and then your torso spontaneously combusts! That definitely qualifies as one of the most dangerous things to do with ether. Actually if you drank hot coffee right after that, I think that would cause it to boil. A lot. So anyways... it would be slightly less exploding-in-your-face if some ethanol and BHT were added. Plus I don't have to keep it around forever... Actually, I could top off a jar with liquid nitrogen. That would stop peroxides... Does anyone know if fisher scientific se
  8. Once it reaches 70% concentration, it becomes capable of instantly vaporizing all of its contents in a very large liquid-to-gas explosion. Careful there... You can get it to exploding concentrations (above 30%) just by evaporating off the water. (It helps if it's in solvent that evaporates faster. The stuff I had was 80% ethanol, 5% H2O2, and 15% mystery solvent.) So, the easiest way is the simplest: evaporate off the water. Tip: Do this outside. Or you will end up like my profile picture... And if you want rocket propellant, try dripping it over silver mesh. That makes it decompose. The
  9. Experimental uncertainty just means that you can't know every aspect of your experiment. If you did, Heisenberg would rise from his grave and get very angry with you...
  10. Does anybody know where an individual can buy diethyl ether (60-29-7), in quantities that are reasonably unlarge (not more than $50)? I know about how most vendors will only ship it out to "educational institutions" and businesses, but if you can but 80% ether as starting fluid, it seems ridiculous that nowhere is there any 90% or 95 or... you get the idea! Thanks for helping!
  11. I think that the sulphuric acid might have aluminum sulfate in it, although I'm not sure what that would do... Plus, even wikipedia is unclear as to what happens under normal conditions. In one place it says you get diethyl ether (a desirable result...), but then it says that this exact same process is used to produce ethylene, without mention of other chemicals coming out of this. Can another acid be used in place of sulphuric acid? If you know a better way of making diethyl ether, please tell me!
  12. I'm pretty sure it's sulfuric acid. That's what it says on the label, and I've never heard of sodium bisulfate being used in photography.
  13. I read on the magical Wikipedia that ethylene can be produced by distilling ethanol and sulfuric acid. So I set up my flasks, and mixed ethanol (denat. w/ methanol) with sulphuric acid from a photography chemical set. But then something unexpected happened: in the flask, small white crystals very quickly formed like sand, replacing about 2/3 of the liquid! What is this, and why did this happen? Thanks in advance!
  14. Thanks. I guess I will try again with graphite, and just see if I can filter it out or something. Besides I'll probably be fine with impurities, as long as there's some chlorate or hydroxide in there somewhere. By the way yt I didn't say to do something unsafe (with the lead batteries and everything)... I just didn't mention precautions, because we already know lead is toxic. But I'm sorry if somebody was actually going to do something dangerous. Actually now that I think about it... the inhaling hydrogen thing was definitely dangerous for most people, but since I live in the middle of 5 a
