Colligative Properties & Osmotic Pressure (Lab – Chapter 13) Introduction: In this lab‚ we are going to observe the difference in freezing point between pure water and salt water. We will also observe the permeability of an egg shell membrane and dialysis tubing‚ acting in place of a human cell‚ when placed into a hypertonic or hypotonic solution. We will observe the changes in size‚ shape‚ and characteristic. Materials and Methods: First we begin this experiment by making an ice bath in
