Experiment 2 - Physical Properties

Procedure:

Part C: Solubility

  1. Use a spatula and scoop a spatula tip of potassium chloride and napthalene into separate test tubes containing about 5 mL of distilled water.
  2. Stopper each test tube and shake.
  3. Repeat steps 1 and 2 using hexane as the solvent.
  4. Record the solubility (i.e. soluble, slightly soluble or insoluble) for each solid in each of the two solvents.
  5. In separate test tubes: mix:
    • 20 drops of ethanol and 2 mL of water
    • 20 drops of hexane and 2 mL of water
    • 20 drops of hexane and 2 mL of ethanol
  6. Record which combinations are miscible and which are immiscible. When you have finished pour any remaining hexane or any mixture which contains hexane into the waste container provided.
