Osmosis
Biology · Secondary 4 · Hard · Osmosis
A dialysis bag filled with 0.3 mol/dm³ sucrose solution is placed in a beaker of 0.1 mol/dm³ sucrose solution. The bag is made of a membrane permeable to water but not sucrose.
What will happen to the bag after 30 minutes, and why?
What will happen to the bag after 30 minutes, and why?
- The bag gains mass because water moves into it by osmosis.
- The bag loses mass because sucrose diffuses out into the beaker.
- The bag gains mass because sucrose diffuses into it from the beaker.
- The bag’s mass does not change because water potentials are equal.
