Which is the best description for the osmotic pressure of a solution?

A: the pressure that needs to be applied to the solution while it is separated from pure water by a membrane, to prevent a net flow of water through the membrane into the solution
B: the force with which pure water moves through a membrane into that solution as a result of its solute concentration.
C: the movement of particles through a membrane, where the movement is caused by a hydrostatic pressure.
D: it is the force of attraction for water by undissolved particles in the solution.

A: the application of a hydrostatic pressure to a solution in order to

oppose and prevent the osmotic flow of water into that liquid is the basis for

assigning a value to that solution for its “osmotic pressure”. Osmotic pressure

is the value of this externally applied hydrostatic pressure. Choice C describes

filtration. Choices B & D are nonsense.
