Investigating Osomosis

Question 1

What different effects do water concentrations have on potato cylinders?

Answer 1

Prepare sucrose solutions in different concentrations from pure to heavily concentrated sucrose solution.
Use a cork borer to cut a potato into the same sized prices divide the cylinders into groups of 3,use the mass balance to measure the. Ass of each group
Place one group in each solution
Leave the cylinders in the solutions for 40 minutes
Remove the cylinders and pat gently with a paper towel to remove excess water fro pm the surface to get more accurate measurements
Weigh each group again and record the results
Only thing that should change is the sucrose solution concentration

Question 2

How to calculate the percentage change.

Answer 2

Percentage change = final mass - initial mass / initial mass
