Two Solutions, a and B, Are Separated by a Semipermeable

Multiple Choice

Two solutions, A and B, are separated by a semipermeable membrane.Which of the following statements regarding their tonicities is NOT correct? Assume the same van 't Hoff factor for each solution.

A) If A and B are of equal molarities, they are isotonic.
B) If the molarity of A is lower than that of B, solvent will flow from B to A.
C) If the molarity of B is lower than that of A, B is hypotonic relative to A.
D) If the molarity of A is lower than that of B, the osmotic pressure of B is higher than that of A.
E) If the molarity of B is lower than that of A, A is hypertonic relative to B.
