There is a liquid capsule inside a cup full of liquid. the cup full of liquid has salt in it and the liquid capsule has no salt in it. in which direction will the solvent flow?

a. from the capsule to the larger cup
b. from the larger cup to the capsule
c. equally between the capsule and the cup
d. the salt does not have to move

A. From the capsule to the larger cup

Explanation:

Solvent movement occurs from region of higher concentration to that of its lower concentration. In the given example,  the liquid capsule has higher solvent concentration since it does not have solute. Presence of solute in larger cup makes it hypertonic solution with respect to the liquid inside cup. Hence, solvent will move from hypotonic solution (liquid in capsule)  to hypertonic solution.
