APHY 201 Osmosis and Diffusion LAB Questions with Correct Answers
Question 1:
The percent change in mass increases as the initial concentration of sucrose increases inside
the
Answer:
concentrations of sucrose inside the bags.
Question 2:
1. Predict what would happen in an experiment if all the bags were placed in a 0.4M sucrose
solution instead of water.
Answer:
bags.
Bag B would decrease in mass, Bag C no change in mass, and Bags D, E, and F would increase
Question 3:
1. What would be different in your results if the membranes were permeable to the solute
Answer:
in mass, but not as much as placed in a beaker of water.
Question 4:
In beaker 1, the solution on the right side of the membrane has a (higher or lower) osmolarity
than the solution on the left side of the membrane
Answer:
into the bag lowering the mass of each bag.
