Question 115

A partially permeable membrane separates a dilute solution from a concentrated solution, and the solute cannot cross. What is the net direction of water movement?

  1. The water has no net movement under these conditions.
  2. The solute crosses toward the dilute side and pulls no water.
  3. The water moves from the concentrated side toward the dilute side.
  4. The water moves from the dilute side toward the concentrated side.Bonne réponse

Explication

Water moves by osmosis from the more dilute side toward the more concentrated side when the solute is unable to cross. Reversing that direction confuses water movement with the direction in which solute might be imagined to spread.
