A dialysis tubing bag (partially permeable membrane) is filled with concentrated sucrose solution and placed in pure water.
After 1 hour, what change is expected in the mass of the bag, and why?
After 1 hour, what change is expected in the mass of the bag, and why?
- Mass decreases because water leaves by osmosis.
- Mass decreases because sucrose diffuses out.
- Mass increases because water enters by osmosis.
- Mass stays the same because no movement occurs.
