solution it was placed in. Bag #1’s solution was hypotonic compared to the solution of beaker #2. Bag #2’s solution was also hypotonic compared to the solution of beaker #2. Bag #3’s solution was isotonic compared to the solution of beaker #2 and Bag #4’s solution was hypertonic compared to the solution of beaker #1. 2. Which bag increased the most in volume? Why? Bag #1 increased the most in size because the solution inside was of a higher concentration of sucrose than that of Beaker #2 so therefore
