Question

List molar concentrations (0.0 M, 0.2 M, etc.) at which water entered the potato strips. Why did water move into the potato strips? Were these solutions hypotonic, hypertonic, or isotonic?

Answer 1

Answer:

- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.

- The solutions are hypotonic to the solution in the potato cells.

Explanation:

According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.

Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
