Title: Colligative Properties & osmotic Pressure
Purpose: The experiment was designed to explore the colligative properties of freezing prefigure depression and osmotic pressure in solutions as intumesce as define colligative properties and discuss membrane permeability and osmotic pressure.
Procedure: There were several different products used to instal for this experiment such as small rubber bands, salt, dab water, 1/8 measuring spoon, di be quieted water, crushed ice, 100ml plastic beaker, digital stopwatch, test tubes, thermometer, 24 well plate, white vinegar, eggs, Karo light syrup, pint jar with lid, glass bowl, funnel, and Dialysis tubing.
