  by several physical methods
• how choice of separation tecniques?

  based type of mixture and difference in the chemical I properties of constituents of mixture
• process of selectively removing a solute from a mixture with solvent? extraction
• the solute to be extracted may be in?

  solid or liquid medium
• the solvent used for the extraction process may be?

  water or water miscible solvent or water immiscible solvent
• the selection of the solvent to be used depends upon the?

  solute or upon requirements of the experimental procedure

  rapid ,simple and inexpensive to perform 2-should yield quantitative recovery of target analytes loss or degradation
• in contrast to the large number of organic compounds that distribute themselves between aqueous and organic phases, the number of simple inorganic compounds that do so quit small.
• the partition of iodine between water and carbon tetrachloride is well known
