Purpose: Determine if Glycerin is polar or non-polar
Materials:
- Scupula
- Test tubes, rack, and stoppers
- Glycerin
- Paint thinner
- Iodine crystals
- Sodium Chloride
- Sucrose
- Safety goggles and apron
Observation: When a polar solution mixes with another polar solution and a non-polar solution mixes with another non-polar solution it dissolves. But when mixing a polar solution with a non-polar solution and a non-polar solution with a polar solution it did not dissolve.
