make sure to tell us your results! sulfuric acid might be present in small concentrations in nature, i.e. hot volcano springs, i remember once someone went into one and their gold necklace completely discolored and corroded. (and gold is hard to corrode)

Well I'm sure 20% nitric acid is more corrosive then 20% hydroiodic acid, no? say your hands are made out of insoluble lead iodide... put them in a bucket of HI, and nothing would happen. put them in a bucket of HNO3, and it would turns your hands into soluble hydroiodic acid and lead nitrate, dissolving your hands right off. (sorry for the gruesomeness)

its like you know how chlorine doesn't eat at pvc... because polyvinyl chloride already has chlorine in it...but it also doesn't eat at glass because it cant replace oxygen in SO2 fluorine eats at glass, so pretty much the only thing you can store fluorine in is Teflon... oh i just got what you said yt, "rubber seals"... lol that was duct-tape., i let it let some air out just to avoid the risk of overpressurizing... on second thought I should have just used a baloon to collect the gas. Merged post follows: Consecutive posts mergedI think bromine could be made out of bromine monochloride (after all, this thread is called extracting bromine) with the use of sodium iodide and chlorine. [ce]BrCl + 2NaI -> NaBr + NaCl + I2[/ce] [ce]Cl2 + 2NaBr -> 2NaCl + Br2[/ce] I'm pretty sure this would work. Before anybody points this out, yes i know excess Cl2 in the second equation is technically capable of reacting with the Br2 to make BrCl again. However, I don't think they react that easily. If that was true, then the I2 from the first equation could also be part of a variety of interhalogens. (IBr, ICl, ICl3)... which i suppose is very possible actually. But I'll save that experiment for some other time... I'm sure all of you are tired of hearing about halogens.

ok UC, I know that picture is horrible and inconclusive. And you could argue that there was moisture in the air which condensed. But I'm pretty sure it was chlorine. But I guess I can't argue that at this point. I'll have to make chlorine again, I need it to precipitate iodine. Maybe a more convincing picture this time.

I'm sorry if this is the wrong section, perhaps it belongs in physics, but how cold is ice + salt + water? I'm wondering because most of the places I look it says like -10 degrees, which seems about right if you use the freezing point depression equation. However, I was easily able to condense a drop of chlorine (I'll get a better picture soon, but here), whose boiling point is -35 degrees celsius, -30f. I used water + ice + a good amount of magnesium sulfate and sodium chloride. I think maybe because I used two different salts, i was able to circumvent the common ion effect... oh, and don't make chlorine.

I don't think that was a hallucination, hydrochloric acid is irritant and it stings me too sometimes if i forget to wash my hands off. Sulfuric and nitric acid- for those you better wear gloves, im sure they're capable of dissolving the skin right off your hand.

chemicals are entertaining...especially at my age... i especially like the halogens, they're the most corrosive group of elements. I'm not suggesting you do this, but a glock would be like a firework if you drop it in a bucket of bromine. You'll get left with a fine powder of metal bromides. you know those acids you saw in movies as a kid, that if you drop on the floor burn through several floors of solid metal? I hate to say most aren't this reactive. Concentrated sulfuric acid and nitric acid are pretty powerful though. And most acids would probably eat through a block of steel eventually. Still I would say that oxidizers are better, except that the only one i can think of that's liquid is bromine. Chlorine is easy to condense into liquid with some ice, salt, and water, its entertainingly corrosive. Liquid oxygen- just watch it on youtube. spill it on a piece of wood, and you'll get an inferno. But just to condense oxygen you'd need liquid nitrogen, its boiling point is like 200 degrees below chlorine's. I wonder if the bullets would go off while the glock is dissolving.

i need some HOCl for an experiment I'm very interested in. Anybody know how I can make this? I can get NaOCl, NaCl, H2O2, MnO2, HCl, NaOH, MgSO4, NaSO4, electricity, and other common materials. And please don't suggest bubbling chlorine through water, it will not work for the experiment I'm doing. Merged post follows: Consecutive posts mergedwould acetic acid(CH3COOH) + bleach(NaOCl) yield sodium acetate(NaCH3CO2) and hypochlorous acid(HOCl) ? if not, does anyone know any similar reactions that would make HOCl? Merged post follows: Consecutive posts mergedahh! these chemistry threads move so slowly... In any case I have concluded that the only way that one could make HOCl (besides dissolving chlorine in water) is to react NaOCl with an acid that has a negative ion more oxidizing than oxygen. For example, 2NaOCl + H2SO4 > Na2SO4 + 2HOCl... that way the oxygen in NaOCl would not dare oxidize an acid (say HCl) to water and say chlorine for example.

lol, we should start a thread "what's so awesome about google calculator".

actually i suppose if its just supposed to be a quick project, you can do some slingshot type thing... 1.7m is more than enough to get a lot of tension on the slingshot... actually yeah, thats much easier and probably better than the chemicals idea...

lol how did i not catch that... yeah i meant 0.999999999999999999999.... google calculator is nice isn't it?

yeah, i looked at your statistics, and as for post #33, i kind of said it as a joke... but its more than a valid point...without going into the details, here's a site. Its also the perfect explanation as to why my first set of statisticts (post#28) disagrees with yours (post#29) but no matter what you say, i still think that HIV doesn't get through the holes in latex on any significant scale.

Yeah, i realize that- because it will take an infinite amount of energy, post #30 i believe, but you can travel at (0.99)[math]^{10000000}[/math] the speed of light, which, if you round it, is the speed of light. ok, that was a smart line. p.s. i seriously got to stop posting on this thread p.p.s. sorry i must have missed what are your main points, twice. p.p.p.s. i like to be the last one to respond, but apparently that's not going to happen. but i think i got the main idea...

nah, i get it...if anything, its only strange once you're at the speed of light... for example say in your rocket, kerosene and liquid oxygen are reacting. Anyone who looks from outside the rocket will see that the molecules are not moving and thus not reacting. No kerosene is being burned. But from inside the ship, kerosene and oxygen are reacting at normal rate. Let's say at that rate, 1 gallon of kerosene is burned an hour. So after an hour, how much kerosene is burned?
