Title: Halogen – halide reactions in aqueous solution

Objective: To investigate the order of oxidizing ability of the halogens Cl2, Br2, and I2 in aqueous solution

Apparatus / Materials: Test tubes, Bromine water ,Br2(aq) ,Chlorine water, Cl2(aq),

                                         Iodine solution,I2 (in KI aq),Potassium Bromide solution( KBr),Potassium chloride

                                         solution(KCl), Potassium iodide solution(KI),Hexane(C6H14)

Procedure:

  1. Reaction (if any) of iodide with chlorine and bromine
  1. About 1mL of Potassium iodide solution is added to each of two test tubes
  2. About the same volume of chlorine water is added to one of these tubes and the other was added with the same volume of bromine water
  3. The test tubes is shake and the color changes is noted-(if any)
  4. A few drops of hexane is added to each tube, shake and allow it to settled  and the color of each layer is noted.
  5. Reaction that taken place is observed and a copy of result is completed in table 11.1.
