A dialysis bag with red food coloring in a 9% NaCl solution is placed in a beaker. The beaker contains a solution that is 4% Naci. The dialysis bag is semi permeable
allowing the movement of water and food coloring.
Based upon the scenario above, what would move across the membrane water, food
coloring, and/or NaCl? For those substances that would move across the membrane,
which direction would each substance move?
