Done Homework 4 e beaker in the illustration below contains two solutions of salt with different concentrations (measured by molarity Mo The two solutors are separated by membranethatus ermeable to both salt and water. A 0.2 M 0 0.9 M B salt salt Which of the following will occur in this container? Net diffusion of water from B to A and of salt from A to B. Net diffusion of water from A to B and of salt from B to A. water across the membrane, but not of salt.

Solution

Option III

Net diffusion of water will occur across the membrane.

The salt solution in A is hypotonic with molarity of 0.2 M and that of B is hyper tonic with molarity 0.9 M.

So the water always travels from high concentration gradient to low concentration gradient (osmosis). So water will travel from A to B and no movement of salt takes place.
