Lab Report: Diffusion and Osmosis
Hypothesis and Prediction:
This lab was done to examine and comprehend how diffusion and osmosis works in diverse molarity of sucrose. Also how the solutions permeates through different mediums.Lab Report: Diffusion and Osmosis Assignment Paper
Methods:
Part A: Diffusion and Osmosis:
A 30 cm piece of 2.5 cm dialysis that has been soaked in water was obtained. The beginning of tubing was tied off, forming a bag with an open end that was rubbed between the fingers till separated. 15mL of the 15% glucose and 1% starch solution was placed into the bag and the ending of the dialysis bag was tied off, leaving some space for the development of the content within the dialysis bag.

The color of the solution was recorded and was tested for the presence of glucose. Distilled water was poured into a 250 mL beaker (two-thirds of a cup) with about 4mL of Lugol’s solution (IKI). The color of the sucrose in the beaker was recorded and was tested for glucose. The dialysis bag was then submerged into the beaker of solution and left to stand for about 30 minutes (or until there was a color change in the dialysis bag or beaker).Once the bag was done soaking in the beaker, the final color of the solution in the bag and the beaker was recorded. The liquid in the bag and the beaker was then tested for the existence of glucose.Lab Report: Diffusion and Osmosis Assignment Paper
