You add a 50% salt solution (NaCl) into a dialysis bag (permeable to both, water and salt) and place it into a beaker with pure water. What would be the net movement of molecules?

a) Water and salt will move out of the bag

b) Salt will move out of the bag and some water will move into the bag

c) Water and salt will move into the bag

d) Water will move out of the bag and salt will move into the bag

e) There will be no net movement of molecules

Solution

Answer:

b) Salt will move out of the bag and some water will move into the bag

Water or salt move from their high concentration to low concentration. Bag consists of high salt and low water concentration when compare to pure water of beaker. So water will move into the bag and salt will move out of the bag
