  1. http://www.humanmetrics.com/cgi-win/JTypes2.asp I'm INTP (Introverted iNtuitive Thinking Perceiving).
  2. I had something similar happen to me when I stupidly used 120 V AC on a sodium chloride solution. I was using two carbon rods as electrodes. The instant I turned it on, there was arcing like crazy in the beaker and steam pouring out of the beaker. The solution was boiling from the heat created. I unplugged it as quickly as I could. The room smelled horribly of ozone for awhile.
  3. Keep in mind that most chems can act as either in different situations, but that aside, here's some things... Common oxidizing agents: halogens, permanganates, perchlorates, nitrates, peroxides Common reducing agents: active metals, Alkali metals bonded to hydride complexes
  4. An equal mixture of the two optical isomers of a substance: dextrorotary and levorotary. When the optical isomer is important in a particular situation, the name of the chem will include the bolded part. The dextro and levo rotary refer the the direction the molecules rotate plane polarized light.
  5. If that works it would likely result in really, disturbingly fine powder.
  6. You could basically say that ox state just tells you how many bonds have been made, and only reflects lost or gained electrons in ionic bonds.
  7. Calcium carbide is really fun stuff to play with. One time I told my mother to hold a piece of it and she had wet hands, she wanted to kill me
  8. I'd imagine it would react with zinc quite well if the zinc was powdered and mixed in the correct molar ratio with sulfur and ignited. The result would be zinc sulfide.
  9. Barium sulfate is actually given to people in suspension form before various tests on the colon. It's safe because its insoluble.
  10. Carbonates get the pH high enough that you get the slippery feel on your hand. Does anyone know exactly how high the pH can be raised with carbonates?
  11. You could electrolyze a sulfide salt resulting in this rxn occuring at the anode S2- ---> S + 2e- Or you could just buy it at the hardware store in the gardening section or at some pharmacies for treatment of acne. It's dirt cheap.
  12. Sodium bisulfate, sold at every pool supply place as solid pH down chemical. It's basically partially neutralized sulfuric acid.
  13. NaCl + NaHSO4 ---> HCl + Na2SO4 Heat the reactants and collect the HCl(g) in a syringe and then dissolve it in water to get hydrochloric acid.
