You Make Two Sucrose Solutions, One 0

question 6

Multiple Choice

You make two sucrose solutions, one 0.5M and one of 2M and go out for lunch. When you return, you realize that you forgot to label the beakers! You remake the solutions, but give the undergrads in your lab an experiment to determine which beaker holds which solution. They fill two balloons, which are semi- permeable to water, but not to sucrose, with a 0.75M sucrose solution. One balloon is then placed in each of the unknown sucrose solution beakers. After several hours, they observe that the balloon in beaker 1 has swelled, while the balloon in beaker 2 has shriveled. This indicates that the solution in beaker 1 was relative to the solution in the balloon, while beaker 2's solution was relative to the solution in the balloon.
