Use the following scenario to answer the question. A beaker containing two fluid compartments separated by a semipermeable membrane is filled with distilled water. In compartment A you place 15 mM of NaCl and in compartment B you place 25 mM of NaCl. The membrane is permeable to both sodium and chloride. Initially, which side has the higher osmotic pressure? As time goes on will the water levels change,and if so how?
