Question
The two boxes above contain the same volume and the same concentration of solute particles. A permeable membrane seperates the two boxes. Where will the water move? a. There will be a net movement of water to the right box. b. There will be a net movement of water to the left box. c. There will be no net movement of water. The water in the right box will stay in the right box and the water in the left box will stay in the left box. There will no exchange of water between the boxes. d. There will be no net movement of water. The water in the two boxes will exchange back and forth equally. e. There will be no net movement of water. A permeable membrane will not allow solutes to pass across the membrane.Explanation / Answer
Answer: Option D is correct.
Explanation:
Water moves from high water potential to low water potential.
Water potential of pure water is the highest i.e. Zero
All solutions contain a negative water potential.
Greater the solute concentration, more negative is the water potential.
In the given example, the number of solute molecules between both the compartments is same i.e. they are isotonic solutions.
So, there will be no net movement of water. However, the water molecules move to and forth between both the compartments and exist in an equilibrium state.
