Question

a. Consider these two solutions: Solution A is prepared by dissolving 5.00 g of MgCl2 in enough water to make .250 L of solutions, and Solution B is prepared by dissolving 5.00 g of KCl in enough water to make .250 L of solution. Which direction will solvent initally flow if these two solutions are seperated by a semipermeable membrane?

b. Assuming that the volumes of the solutions described in question 4 are additive and igoring any effects that gravity may have on the osmotic pressure of the solutions, what will be the final volume of solution A when the net solvent flow through the semipermeable membrane stops?

Explanation / Answer

a)   solvent will move from MgCl2 solution to KCl solution , because MgCl2 solution concentration is less compared KCl solution concentration. always solvent moves from high concentrated solution to low concentrated solution.

b) final volume of the solution A will decrease as solvent left from it.
