Stealthspy58 Posted April 23, 2008 Share Posted April 23, 2008 I am trying to create Nitrogen Triiodide (Iodine & Ammonia) for one of my weekly demonstrations. Is there an alternitive route I can use to do this because Iodine Crystals are very expensive. Is there another way to get or change Iodine into an Iodine Crystal?

YT2095 Posted April 23, 2008 Share Posted April 23, 2008 "weekly demonstrations"? explain more about this, something doesn`t quite fit the picture here! Link to comment Share on other sites More sharing options...
person Posted April 24, 2008 Share Posted April 24, 2008 By heating tincture of iodine alcohol evaporates and the iodine sublimides... you could place a glass beaker (containing cold water) above this and hope that the iodine crystalizes on the surface...nt sure if this would work bt worth a try Link to comment Share on other sites More sharing options...
tanz Posted May 18, 2008 Share Posted May 18, 2008 An easier way to percipitate iodine crystals from tinct would be to add to 100 ml dh2o stir then add 50 ml H2So4 slowly stir (it will become a little warm take caution) then add 5 ml NaOCl Sodium hypochlorite solution, commonly known as bleach. Now watch as the the crystals percipitate to the bottom. Link to comment Share on other sites More sharing options...
SkepticLance Posted May 18, 2008 Share Posted May 18, 2008 This is one of those experiments that kids love (big loud noise!) but adults should discourage since it involves an unstable, and explosive substance. When I was a teenager, we used to add ammonia to tincture of iodine till it went clear. We soaked it into filter paper and hung the paper up to dry. Explosive paper, whoopeee! However, not the safest of activities. Link to comment Share on other sites More sharing options...
hermanntrude Posted May 22, 2008 Share Posted May 22, 2008 My advice is to try and save up for some iodine crystals. they go a long way... once you have some u won't need to buy any more for years. Also If you do get some, don't use more than about 0.3g of iodine for the reaction or the sound of the explosion might be hazardous to hearing. I used 0.4 g once and my ears rang for about 10 minutes afterwards Link to comment Share on other sites More sharing options...
YT2095 Posted May 22, 2008 Share Posted May 22, 2008 adults should discourage since it involves an unstable, and explosive substance. indeed, so no more "recipes" in here please, else Hazmat warning(s) will be issued! the OP didn`t ask for an NI3 synth anyway.
