Diffusion
Biology · Secondary 3 · Medium · Diffusion
A student investigates diffusion using two beakers. Beaker X contains 0.1 mol/dm³ salt solution and beaker Y contains 0.5 mol/dm³ salt solution. The beakers are connected by a tube filled with the same salt solution and no membrane. In which direction will there be a net movement of salt ions by diffusion?
- From X to Y only
- From Y to X only
- Equally in both directions so no net movement
- No movement because a membrane is absent
