Diffusion and Osmosis: Using Dialysis Tubing and Investigating Solute Concentration Purpose: The purpose of this lab was to use dialysis tubing to model diffusion across the cell membrane. Through this, examinations were conducted to identify the influence of solute concentration on osmosis. Background: A cell membrane is a cell’s interface with its surroundings; it acts as a barrier.
Diffusion and Osmosis Lab 1 Lab group: Period: Date: INTRODUCTION: In order for cells to interact with their environment, chemicals, including water, must be able to move across the cell membrane and across the cell. Movement within the cell occurs by a process known as diffusion. Molecules move across the cell membrane by a related process known as osmosis. Diffusion is the movement of.
Osmosis is the diffusion of water from a high concentration to a low concentration and water was the variable being tested in this activity because it is what made the mass increase for every sucrose solution. The amount of sucrose solution, dialysis bag, and time could all influence the outcome of this experiment. The higher the amount of sucrose causes for more water to move into the.
OSMOSIS AND DIFFUSION PURPOSE: To see the effects of a permeable membrane. HYPOTHESIS: If the water with iodine diffuses through the bag, then i think the starch will change color. The reason why I think that the water will diffuse through the bag because the concentration gradient outside the bag is more than inside the bag.
