Biology · Secondary 4 · Hard · Osmosis
A dialysis bag containing 0.2 mol dm⁻³ glucose solution is placed in a beaker of 0.6 mol dm⁻³ glucose solution. The membrane is permeable to water but not to glucose.
What happens to the volume of solution inside the bag after some time?
What happens to the volume of solution inside the bag after some time?
- It increases because water enters the bag by osmosis.
- It decreases because water leaves the bag by osmosis.
- It stays the same because glucose cannot move across the membrane.
- It increases because glucose diffuses into the bag.
