Biology · Secondary 4 · Hard · Osmosis
A dialysis tubing bag (partially permeable membrane) is filled with distilled water and placed in a beaker of concentrated sucrose solution.
After 30 minutes, what happens to the mass of the bag and why?
After 30 minutes, what happens to the mass of the bag and why?
- Mass decreases because water moves out of the bag by osmosis.
- Mass increases because water moves into the bag by osmosis.
- Mass decreases because sucrose diffuses out of the bag into the beaker.
- Mass stays the same because no net movement of water occurs.
