  1. how strong is sulfourous acid anyway? ph of four probaly.
  2. i always thought ammonium hydroxide was a solid for some reason, but now that i think of it, ya, it would be disolved ammonia in water. for making ammonia, heat an ammonium salt with a weak alkali. I use ammonium chloride and calcium carbonate.
  3. i think K will hold onto OH pretty tightly, maybe a double replacement with sodium carbonate will work
  4. If you bubble it through water you get sulfurous acid. If you bubble it through H2O2 you get sulfuric acid. The H2O2 is donating its extra oxygen to the reaction to get H2SO4. Im sure there is allittle sulfuruos acid because there is also water in the solution. budullewraagh wrote: i think you'd need a rhodium or platinum catalyst for that. the activation energy for the oxidation of SO2 to SO3 is too great and H2O2 just isnt strong enough of an oxidizing agent for that My response:H2O2 is a fairly strong oxidizing agent.
  5. ive thought about sanding aluminum in a beker of water with sand paper, then i would add H2SO4 to it to see the reaction, but then realized that the oxide layer will probally still form because there is always allittle air dissolved in water.
  6. You could react some copper with H2SO4, but this would take along time, unless you have Cu powder, wool, or possibly foil. I just bough some copper sulfate from ebay. I bought it from a gardeners store on there, but it came as being 99 percent copper sulfate. Pretty good stuff and cheap for amount. Heres the link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1269&item=3810468634&rd=1&ssPageName=WD1V
  7. Why do they call hydrogen peroxide hydrogen peroxide. Shouldnt it be called hydrogen dioxide. My only guess is that it is called this because there are also two hydrogens. I can see with sulfur dioxide SO2, because there is one sulfur. Two oxygens to one sulfur, hence "sulfur Dioxide". But this means that water would be Hydrogen Dioxide instead of hydrogen oxide. Is there just some type of exception with hydrogen that makes it have these wierd names, or am i just trippin.
  8. It might be possible, but just extremeley unstable. Probaly impact sensitive. Try a google search on magnesium trioxide
  9. some one said that manganese dioxide + H2O2 will make oxygen and permanganaic acid. Last time I checked manganese dioxide just catalyzed the H2O2 to H2O and O2. If you take three percent H2O2 and add manganese dioxide, you will get oxygen being produced. When this has ceased you add more and it starts up again. You can do this an infinite amount of times (of course your reactants will get extremely dilute
  10. For making chlorine with HCl and KMnO4, try manganese dioxide, its probaly better, that what the demos in my book use.
  11. You can also add a solution of calcium hydroxide (i make and filter out the solids from calcium carbide, then you can light the acetylene too) to a solution of sodium carbonate or hydrogencarbonate. YTou get a nice white precipation reaction.
  12. dude, thats the same thing i do, i have a lab, bought chemicals online and from those chemicals ive made tons more. I have bought alot of lab equipment also, and made some of it too (bunsen burner, burner stands,any thing that is found in a lab and is constructed of metal). When your in your lab, its not that your trying to make some new incredible thing, but your just doing it for the hell of it, just to experiance chemistry. I feel i am right where you are in chemistry, we have alot of the same chemicals. As with the original question. I have done alot, but the one that always sticks in my mind was when i created ammonia solution. Among all the expirement, this one sticks. So the ideal is to heat an ammonium salt (use ammonium chloride, it works good) with an alkali (preferably calcium hydroxide). I used calcium carbonate. You can do this in an erlenmeyer flask, and have a stopper with a hole. Run a rubber tube to another erlenmeyer flask thats half filled with water. Dont let the hose hit the water when this is going, because ammonia gas is extremely soluble in water and the hydrogen oxide will suck back into your flask thats being heated and then convert quickly to steam, and blow out the stopper realesing the ammonia, then you gotta bail. If when this is happening and your tube is just right above the water in the second flask, the ammonia will immedietly dissolve, and there will be no danger of the gas. This is cool, and i did this because i wanted ammonia for no reason (actualy, to add to my chem collection.) You can also try bubbling sulfur dioxide through H2O2 to get H2SO4. Theres tons of them, and seriosly, if you want to share idea, because were at probaly around the same place in chemistry, just email me and i will tell you everything ive got. You can email me at djeglinski@gmail.com Oh, and how did you get your H2O2, you said you synthesized it yourself. I make MY 50% by boiling antiseptic three percent (EXTREMELY DANGEROUS) down. Its a bad idea but i dont know where to buy H2O2! Here is a small website i made probaly a year ago, and have progressed alot in chemistry from then, this is alittle more basic in chemistry then i am now. It has a bunch of neat reactions that realy are pretty cool. http://www.freewebs.com/chemicalrecreations/
  13. There should be a pyrotechnics forum. There is alot of science in pyrotechnics.
  14. they seem a little expensive, maybe somewhere else
  15. Ya, i meant at elevated pressusers Can superfluidity occur in other element than helium?
  16. H2SO4

    "YT2095 Wrote "Agreed, I use borax (sodium Borate) and sugar mix, around the edges of my raised beds in the garden as an ant killer, it works great :)" What if your dog/cat/watever eats it. Do the ants carry this off to eat because it has sugar in it? It would make sense
  17. H2SO4

    Help Required

    I dont know if your just rying to make boric acid for just making chemicals to ad to your collection ( i do this alot) or if you actualy need some real quick . I f you need some real quick , you can go to a drug store, and they should carry some (of reasonable purity) by the glycerin. This is where i get my boric acid.
  18. I guess at decreased pressures they could solidify helium, i don't see why not.
  19. Does anyone know where to get gallium, ive trolled ebay and cant find any.
  20. If i where you, id use copper and zinc. They have a pretty large difference in terms of reactivity, and are both cheap metals.
  21. YT2095 wrote: remember, there`s a very FINE dividing line between a rocket engine and a Pipe Bomb! I totaly agree. A rocket engine is basicaly a firecracker that vents so i doens't explode (but the mix is alittle slower burning) If your gonna make your own rockets, just do small stuff for beggining, like bottle rockets. I usauly just take some black powder, and some printer paper, take a small piece of it, like 3 inches long and 1.5 inches wide. I then crease the paper, put some black powder in the crease and fold it up tightly, and seal one end with duct tape, and wrap it in only one layer of duct tape to hold it all together. Then tape a wood skewer on it and squeez it with a vise or pliers, but not to hard. And your done (always use fuse, though, and bail when the fuse is lighting, because it is nature of rockets for them to change directions if not perfectly balanced. If you start out small, youll be more prepared for the big stuff, but just take the hobby slow.
  22. i dont know much about KIO3, but could you possibly slowley boil the solution to make it more concentrated, but would this make it the KIO3 decompose or somethin, otherwise this would work.
  23. I have a periodic table that shows the crystal structure of all the elements. I knew metals had crystal structures, but i didnt know that oxygen was crystaline and same with helium. Are they just saying that the altropes of these elements are crystaline (like sulfur and phosporus).
  24. It just makes your head hurt.
  25. Back to the oxides. I like the bismuth oxide and its crystals, The crystals remind me of an aztec city, they realy are quite buitiful. Copper coxide is also very awesome, same with iron oxide, when they are still thin, otherwise, they turn black. I heard nickel and titanium do this to. I think a bunch of the transitions do. Anyway, where can i get some gallium. Ive just been scouting ebay for some but i can only find Ga and indium alloys. I think the only thing that sucks with Ga is that it stains skin, but so does alot of things, it cant be worse than KMnO4. I just wish mercury wasnt so toxic, otherwise that would be sweet
