1. For each of the bags, identify whether the solution inside was hypertonic, hypotonic or isotonic in comparison to the beaker solution it was placed in.
2. Which bag increased the most in volume? Why?
3. What does this tell you about the relative tonicity between the contents of the bag and the solution in the beaker?
4. What would happen if bag 1 is placed in a beaker of distilled water?
5. Osmosis is how excess salts that accumulate in cells are transferred to the blood stream so they can be removed from the body. Explain how you think this process works in terms of tonicity.
