A semipermeable membrane separates two solutions of different concentrations. Identify which of the following statements are correct regarding osmosis and reverse osmosis.
A A solvent can ideally move in both directions through a semipermeable membrane.B A pressure equal to that of the osmotic pressure will result in reverse osmosis.C The movement of the solvent particles from a concentrated solution to a dilute solution is known as reverse osmosis.D Osmosis occurs when the solvent molecules move from a solution of higher solute concentration to a solution of lower solute concentration.E Solute particles can move in both directions through a semipermeable membrane.

Osmosis: It is defined as the movement of solvent with the help of selectively semipermeable membrane into a region of where high solute concentration is present to equalize the concentration of solute on the both compartments.

Reverse osmosis: It is defined as the movement of the high concentration solvent is forced onto the lighter concentration side with the help of mechanical pressure.

Answer:

C. The movement of the solvent particles from a concentrated solution to a dilute solution is known as reverse osmosis.

A. A solvent can ideally move in both directions through a semipermeable membrane

Explanation:

When osmosis occurs, solvent is moved from a region of lower concentration to a region of higher concentration through a semipermeable membrane. For example, if a fresh water fish is introduced into saline water, the fish quickly looses water due to osmosis and dies.

Osmosis is driven by osmotic pressure. Reverse osmosis is a process by which a solvent passes through a porous (semi permeable) membrane in the direction opposite to the direction for natural osmosis when subjected to a hydrostatic pressure greater than the osmotic pressure. Hence the answer choices above.
