When solutions of different osmolarities are separated by a membrane that lets water but not solutes pass through, water will move from the side with lower osmolarity (high concentration of water) to the side with higher osmolarity (lower concentration of water). If the pressure greater than the osmotic pressure is applied the water (solvent) from the solution side starts moving towards pure water. Osmosis, or as it is currently referred to as forward osmosis, has new applications in sepn. The process of reverse osmosis has proven to be the state-of-the-art method for removing salt from seawater and increasing access to clean water. When you dissolve one or more solutes into a solvent, you get a solution. CONCEPTS OF BIOLOGY 1ST CANADIAN EDITION.
