What is osmosis?

• The movement of solute particles across a membrane.

• The diffusion of water across a semi-permeable membrane.

• The active transport of water molecules.

• The process of dissolving a solute in a solvent.

If a solution has a high concentration of solute, what does that imply about its water concentration?

• It has a high water concentration.

• It has a low water concentration.

• Water concentration is unrelated to solute concentration.

• Water concentration is always 50%.
