Below is a diagram representing two chambers containing solvent A, separated by a semipermeable membrane (a dashed line) which allows only solvent A to pass through. If a solute X is added to the chamber on the left, which diagram below best represents how the system will respond in order to reach a new equilibrium?

Below is a diagram representing two chambers containing solvent A, separated by a semipermeable membrane (a dashed line) which allows only solvent A to pass through.  If a solute X is added to the chamber on the left, which diagram below best represents how the system will respond in order to reach a new equilibrium?

Quizplus · Accepted Answer

When a solute X is added to the chamber on the left, the concentration of solvent A on the left decreases, allowing solvent A to move from the right chamber to the left chamber through the semipermeable membrane until equilibrium is reached. This results in an increase in the concentration of solvent A on the right side and a decrease in the concentration of solvent A on the left side. Choice B represents this scenario where solvent A moves from the right chamber to the left chamber until a new equilibrium is reached.
