A beaker contains two compartments.Compartment A (CA) contains a 10% salt solution and Compartment B (CB) contains a 20% salt solution.The membrane is permeable only to water.At equilibrium,the volume in
A)CA is greater than the volume in CB.
B)CA is less than the volume in CB.
C)CB is less than the volume in CA.
D)CA is the same as the volume in CB.

Question

Quizplus · Accepted Answer

Due to the difference in concentration between CA and CB, water will move from CA to CB through the membrane in order to dilute the higher concentration of salt in compartment B. This will cause compartment A to shrink in volume while compartment B will expand. Therefore, CA is less than the volume in CB at equilibrium.
