Question
In osmosis, water moves across a selectively permeable membrane from a solution ofA.higher solute concentration to a lower solute concentration until all of the water is on one side of the membrane.B.lower solute concentration to a higher solute concentration until all of the water is on one side of the membrane.C.lower solute concentration to a higher solute concentration until equilibrium is reached.D.higher solute concentration to a lower solute concentration until equilibrium is reached.
Solution
The correct answer is C. In osmosis, water moves across a selectively permeable membrane from a solution of lower solute concentration to a higher solute concentration until equilibrium is reached.
Here's the step by step process:
-
Osmosis is the process of diffusion of water across a selectively permeable membrane.
-
The water molecules move from an area of lower solute concentration (more water molecules) to an area of higher solute concentration (less water molecules). This is because the water molecules are free to pass across the membrane, but the solute molecules are not.
-
The movement continues until the concentration of water is equal on both sides of the membrane. This state is called equilibrium.
-
Even after equilibrium is reached, the molecules will continue to move back and forth across the membrane, but there is no net movement of water. The number of water molecules moving in one direction is equal to the number moving in the other direction.
