A beaker contains two solutions of salt dissolved in water. The two solutions have different concentrations (measured by molarity, M) and are separated by a membrane that is permeable to salt. Side A has 0.2 M of Salt and Side B has 0.9 M of salt.

Which of the following statements is TRUE?

a) There will be a net movement of salt from side A to side B

b) There will be no net movement of salt

c) There will be a net movement of salt from side B to side A

c) There will be a net movement of salt from side B to side A

Explanation:

According to the given information, the solution at side A is hypotonic to the solution at side B. The separating membrane is permeable to salt and would allow the movement of salt from the hypertonic side B to the hypotonic side A. Transport of substances down their concentration gradient is a passive movement and occurs from the region of higher concentration of the substance to that of its lower concentration.
