Conduct an activity to demonstrate osmosis

Question 1

Method

Answer 1

1. Place sucrose solution into visking tubing (semi-permeable membrane), Tír it and get the mass.
2. Place water (control) into visking tubing, tie it and get the mass.
3. Place both visking tubing until water and leave for an hour.
4. Remove the visking tubing, dry them and re weight them.
5. Record the difference in mass and appearance of visking tubing.

Question 2

Results

Answer 2

1. The visking tubing with sucrose increased in mass due to osmosis whereas the control did not change in mass.
2. The sucrose visking tubing were more turgid than before.
