Experiment 6 - Solutions

Procedure:

Part B - Compare the Relative Solubility of Two solutes in Two solvents

INSTRUCTOR DEMONSTRATION

  1. Add about 5 mL of water and 3 mL of hexane to a test tube carefully, without mixing. Observe the relative position of each liquid. (Note: Avoid inhaling hexane vapours since they are toxic).
  2. Add a few crystals of iodine, I2, to the test tube carefully, without mixing. Insert a stopper and leave standing for about 30 minutes. Observe the appearance of each layer.
  3. Repeat steps 1 and 2 except add copper(II) suplfate pentahydrate, CuSO4· 5H2O, crystals instead of iodine, I2, crystals.
