  • 1 Note that in the original version of this experiment, the solvent used was tetrachloromethane, but with restrictions on the use of chlorinated hydrocarbons this compound and related solvents should not be used in this experiment even if stocks are still held. (rsc.org)
  • This method was first developed by Benesi and Hildebrand in 1949, as a means to explain a phenomenon where iodine changes color in various aromatic solvents. (wikipedia.org)

  • Isolating the iodine from this solution can be done by solvent extraction , followed by evaporation of the solvent. (rsc.org)
  • Safety considerations involving the use of the flammable solvent rule out the solvent extraction of the iodine as a class experiment for larger groups. (rsc.org)
  • However, with suitable small groups, extraction of the aqueous iodine into a non-polar solvent to show its characteristic purple colour could be carried out on a test-tube scale, using only a few cm 3 of the solvent. (rsc.org)
  • This was attributed to the formation of an iodine-solvent complex through acid-base interactions, leading to the observed shifts in the absorption spectrum. (wikipedia.org)
