a more concentrated solution to a more dilute solution
|
Detailed explanation-1: -During osmosis, the movement of water normally occurs from dilute solution (low solute concentration) to concentrated solution ( high solute concentration). Now, if external pressure is applied to the dilute solution, more water molecules will move across the membrane towards concentrated solution.
Detailed explanation-2: -Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high concentration of water) to a concentrated solution (low concentration of water).
Detailed explanation-3: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.
Detailed explanation-4: -Very simple explanation for osmosis is the concentration of water explanation-water in pure water is simply more concentrated than water in solutions because the solute has to take up some room in the solution.
Detailed explanation-5: -A dilute solution contains a high concentration of water molecules while a concentrated solution contains a low concentration of water molecules. Osmosis refers to the movement of water molecules only. Water molecules move from solution one to solution two.
