An eager AP Biology student interested in studying osmosis and the movement of water in solutions took a dialysis bag containing a 0.5 M solution and placed it into a beaker containing a 0.6 M solution. After the bag has been sitting in the beaker for a while, what would you expect to have happened to the bag?
There will have been a net flow of water out of the bag, causing it to decrease in size.
There will be have been a net flow of water into the bag, causing it to swell in size.
