  1. dont forget all those organics that cannot be classified as acids, bases or salts.
  2. it wouldn't. and it would be a little difficult to convert it to a salt. perhaps you could try complexing it to form an europate? but then again, i dont know this is possible. works with aluminum though. perhaps: 2NaOH+Eu2O3+3H2O --> 2NaEu(OH)4
  3. just a note, acetone also works with polystyrene.
  4. plus the great heat change. you end up boiling water im sure in addition to yielding H2, just a thought.
  5. entropy is a measurement of the amount of energy in a physical system that can be used to do work. enthalpy is the internal energy of matter+pressure*volume
  6. you could probably reduce it with LAH at high temperatures in an inert atmosphere.
  7. i've been exposed to chlorine gas on numerous occasions. a half-lungful made me cough for a few minutes and then i didnt get pulmonary edema. the other time i smelled the gas and coughed maybe three times.
  8. oh i noticed how you mentioned to neutralize the solution. if you were to neutralize it with NaOH, you still would have water involved, which would explosively react with the NaBH4. "Also I recently did a reduction with an NaBH4 reducing solution imediatley followed by adding HCl (which is a necessary step), and it definatley didn't explode on me." yes, i believe that would be because the NaBH4 oxidized before you added the acid...
  9. yes, it was used in world war I. it also killed very few people. in the first world war, trenches were used. the chlorine wasnt pleasant, so people would leave the trenches, coughing, at which time, they would be mowed down by machine gun fire. chlorine gas itself is responsible for a very small percentage of fatalities in combat. a quote from wikipedia: at second battle of ypres: " "90 men died from gas poisoning in the trenches; of the 207 brought to the nearest dressing stations, 46 died almost immediately and 12 after long suffering." Chlorine was inefficient as a weapon. It produced a visible greenish cloud and strong odour, making it easy to detect. It was water-soluble so the simple expedient of covering the mouth and nose with a damp cloth was effective at reducing the impact of the gas. Chlorine required a concentration of 1,000 parts per million in order to be fatal, destroying tissue in the lungs. However, despite its limitations chlorine was an effective terror weapon and the sight of an oncoming cloud of the gas was a continual source of dread for the infantry." and while it's "dangerous," consider everything in moderation. basically, one would have to lock one's self in a room with significant amounts of chlorine gas in order to die. if you do an experiment outside and you stand 5 feet from a reaction vessel that spews a few moles of chlorine upwards, you wont die. you'll cough a little. you MAY get pulmonary edema. still, again, the smell becomes unbearable before concentrations become high enough to cause any significant damage, so you'll know when to run.
  10. glycerine has 3 carbon... i would be very careful about using acids and then NaBH4. in fact i wouldnt advise you to do so, as the NaBH4 would explosively react with the acid.
  11. no it isnt. it's very difficult to kill yourself with chlorine. the smell becomes unbearable LONG before you get anywhere near a lethal concentration. i got a full lungful once and coughed for 3 minutes and i was fine. didnt even get pulmonary edema. well, maybe a very mild case but it wasnt bad at all. plus, the fbi isnt worried about chlorine. anyway, i'd explain, but im sure jdurg would rather do so, as he seems to loove ampouling gases:D
  12. i doubt that they would use h2o2 or hno3
  13. decided to walk out in quicksand-like mud under a bridge in cape cod as the tide was coming in
  14. eh, there are soluble sulfates and sulfate complexes/hydrates
  15. glass varies in purity and composition. could you please specify?
  16. i wouldnt be so sure the Cl- anion is more active than an alkyl oxide radical. plus, it's not always healthy to neutralize the acidity of one's stomach
  17. what plastic are we talking about? i can find you a solvent, but not all plastics are the same.
  18. did you ever check the radiation levels in your lungs? i think you should talk to a doctor about this. better safe than sorry
  19. good luck with that. how did you "make" your rp? please dont tell me you used thousands of books of matches.
  20. incredibly more so, at equal concentrations, only because of the insanity that is fluorine
  21. basically you have a piece of copper submerged in a solution of a cupric (or you could use a cuprous) salt and a piece of zinc submerged in a solution of a zinc salt. these solutions are connected by a wire as well as a solution of an aqueous salt, the cation of which has greater activity than zinc and copper. basically, the zinc metal is oxidized, and the electrons are transferred to the copper metal. immediately, the cupric (or cuprous) salt is reduced to copper metal, which is deposited on the plate. the anions from the cupric/cuprous salt migrate over the "salt bridge" to the zinc solution, where they balance the charge difference created by the oxidation of zinc.
  22. well, the salvinorin-a in salvia divinorum actually does affect opoid receptors (which is surprising for a hallucinogen), and it's legal, so go figure.
  23. your friend did this? cancer isnt fun and games, man. how long ago was this?
  24. that would be due to the atropine, hyoscyamine, and scopolamine naturally found in datura, as well as atropa belladonna (nightshade), among others. these alkaloids competitively inhibit acetylcholine, hitting the muscarinic acetylcholine receptors. being as powerful as they are, they just may kill the daphnia. i actually have some extract of atropa belladonna that i use for medicinal purposes, so i may try to use that.
  25. it's not in the merck index. it's pretty much useless; it cannot be metabolized and what good are sugar salts anyway?
