• Resumen

  • A simple and safe classroom demonstration showing the production of sodium iodide (NaI) crystals from elemental sodium and elemental (molecular) iodine is presented. The demonstration, which is quite impressive, naturally fits into the discussion of ionic bonding and the alkali halide crystals. It is best suited for a classroom or laboratory containing fewer than 75 students. Suggestions are made for using the product in other topics covered in the course.
