  1. Just react it with some HCl, the Fe will go into solution, and the S will be given off as H2S.
  2. Ok, so If i dissolve the flint in water, can I react that with the oxalic acid, or should I dissolve it in nitric or something along that road?
  3. If I recall correctly, if C electrodes are used, then NaCN is produced, not exactly a fun compound to be working with
  4. Ok, most everybody knows that the cheap mischmetal used in firestarters is pretty much an alloy of Ce and Fe, along with trace amounts of Mg, Mn, etc. My goal is to extract the Cerium in a salt for from this. I have looked around, and found that Cerium Oxalate is not water soluble. I know that Iron Oxalate is quite water soluble from my mineral-collecting hobby (oxalic acid is used to turn ferroferrous dirt deposits in quarts in to iron oxalate, which then goes into solution, leaving the quartz spotless). Therefore, I should be able to have Cerium Oxalate precipitate out of a solution of the dissolved mischmetal by the addition of oxalic acid. My question is, should I just dissolve the mischmetal directly in oxalic acid, or should I dissolve it in something else, and react that with oxalic acid? If so which acid should I dissolve the mischmetal in? I will try to post pictures with my results (if my results end up positive).
  5. Uranium dust is possible? I thought it was pyrophoric...
  6. There is a biology forum right below the chemistry forum.
  7. Wouldn't a very dilute soln of Nitric Acid color it yellow?
  8. Show the exothermic reaction of anhydrous CuSO4 and H2O, and the endothermic reaction of NH4NO3 and H2O.
  9. You could always use the search tool
  10. As many of you may know, I collect minerals. Recently, I bought a book that describes mineral tests with Cobalt Nitrate. Any ideas of how I could make it?
  11. Why not make nylon, that is quite fun.
