If ʺAʺ contains 2% NaCl and is separated by a semipermeable membrane from ʺBʺ which contains?
If ʺAʺ contains 2% NaCl and is separated by a semipermeable membrane from ʺBʺ which contains
10% NaCl, which event will occur?
A) NaCl will flow from ʺAʺ to ʺBʺ.
B) NaCl will flow from ʺBʺ to ʺAʺ.
C) Water will flow from ʺBʺ to ʺAʺ.
D) Water will flow from ʺAʺ to ʺBʺ.
E) none of the above
The answer is D. I thought water flows from a high to a low concentration and it would be C.

Well, it does, but you must then look for the water concentration which is 98% in A and 90% in B.
The semipermeable membrane could make you think of is an osmosis technique. In osmosis, the solvent (subsequently water) will bypass in the process the membrane attempting to attain equivalent concentrations in the two factors of the membrane. this implies solvent will flow from the backside concentration of solute (making this a greater concentrated answer: much less solvent, greater concentration) to optimum concentration of solute (making it a miles less concentrated answer: greater solvent, much less concentration). Then water will bypass from A (much less concentrated) to B (greater concentrated); decision C.
