Question

these questions are similar to those on the test. 1. diffusion is the movement of molecules from __________ to __________ concentration. 2. the diagram below shows a solute dissolving in a solvent. draw what the solution look like after diffusion reaches an equilibrium. 3. how does osmosis differ from diffusion?

Explanation:

1. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
2. At equilibrium in diffusion, the solute molecules will be evenly distributed throughout the solvent. So the diagram should show the dots (solute) spread out uniformly in the container.
3. Osmosis is a special type of diffusion. Osmosis specifically refers to the diffusion of water molecules across a semi - permeable membrane, while diffusion can refer to the movement of any type of molecule from high to low concentration without the requirement of a semi - permeable membrane.

Answer:

1. an area of high; an area of low
2. Draw the solute molecules evenly distributed throughout the solvent container.
3. Osmosis is the diffusion of water across a semi - permeable membrane, while diffusion is the movement of any molecule from high to low concentration without the need for a semi - permeable membrane.
