In lab, a dialysis bag was filled with a 10% sucrose solution and placed in an unlabeled beaker filled with clear liquid. The dialysis bag was made of a semipermeable membrane that allowed the free passage of water, but was not permeable to sucrose. After two hours, the bag in the beaker decreased in size, lost volume, and became flaccid. Therefore, at the beginning of the experiment, the solution in the bag was compared to the solution in the beaker. g
