Abeaker 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.
