  1. There is another way (if your looking for one) to produce iodine. you could use Potassium iodide (25g for $17.30 from Alfa Aesar) and use Muriatic acid (a big jug of it for $5 from a hardware store) and Hydrogen Peroxide (3% solution from drugstore) with a coffee filter and you have elemental iodine (look here for full process ) then you can purify it buy vaporizing it in a beaker with a ice water filled bell flask on top and the pure iodine will collect on the bell glass i hope it helps albgk
  2. thanks UC ill try that, but i have another idea for a process, ill tell everyone if it works it seems to be safe but it will take me awhile but ill try. wish me luck thanks albgk Merged post follows: Consecutive posts mergedOk heres what I have from my procedure It was a partial success. My procedure was like my 2nd to last post (with the flask and the buring sulfur) except that i put an angled glass tube in it to pull in more oxygen (i dont know if it worked). Also i attempted to boil the H2O2 to remove the H2O in the solution (i only had 3%) but that did not work well. Now to the good part... i lit the sulfur and lowered it in and hey the blue flame was still there... once i felt i had a sufficient ammount of SO2 in the flask i removed the spoon and corked the flask... then i gave the flask a shake, for a very long time, and I still had some SO2 left in there. I then took the liquid and put it on some lithmus paper and it turned red, but when i put i put it in sugar... the sugar turned yellow and did nothing else =(. The verdict- i believe that i created alot sulfurous acid and a trace ammounts of sulfuric acid (i hope) I now need suggestions on how to perfect this procedure thanks albgk
  3. I do believe that i was using a rubber stopper and ruber tubing... at the time of the suckback both rubber items seemed to be fine. While i was cleaning up the mess i did wash the stopper and tubing and they still seemed fine. Im about to go check them out again (hopefully they are still there). Im also going to try something else (please tell me if you think this will work) Im going to put H2O2 in a erlenmyer (bad spelling) flask then i will take a bent metal spoon with sulfur in it, light the sulfur on fire, and then lower the flaming sulfur (producing SO2) into the flask of H2O2. Ill give it a shake (carefully ) and i hope that will produce H2SO4. I think this will work (not so efficiently as bubbling SO3 with water) If i have a problem in this procedure please tell me (im going to wait on the ok from you guys this time ) Thanks albgk
  4. I recently attempted to make H2sO4 here was my procedure: I heated Sodium Bisulfate (NaHSO4) in a test tube- this should have made gaseous SO3 the test tube had a tube on the end that i used to bubble the SO3 through water in a collection beaker with a peice of Lithmus paper in it (so i could tell if it was working).... Then came my problem... I was heating it and it was letting off water vapor (another bi product of heating NaHSO4) then i smelt sulfur and suddently the water (or possibly sulfuric acid) shot back up the tube and blew up my test tube. I was cleaning up this mess (thinking it was a complete failure) when i noticed my Lithmus paper had turned red. I think this could have been sulfuric acid, but i couldnt do any tests with it because i was busy picking up broken glass, and wiping up mystery liquid. The verdict- It is hard (and dangerous) for a home chemist with basic supplies (chemicals, testubes, burners, ect.) to make sulfuric acid. Now that i have told my story, if any of you chemistry wizzes notice a flaw in my procedure please let me know because i would like to perfect an easy way to make sulfuric acid thanks albgk
