Assume you had a balloon made of some highly flexible semiperiable membrane. The balloon is filled entirely with a 0.2 M solution of some solute as well as is submerged in a 0.1 M solution of the same solute. Initially the volume of the solution in the balloon is 0.25 L. Presuming the volume outside the semipermiable membrane is large, what would you expect for the solution volume inside the balloon once the system has come to equilibrium through osmosis.
a) The volume of the solution would increase
b) The volume of the solution would decrease
c) The volume of the solution would remain the same
