I keep getting “Osmosis” questions wrong in Solutions & Colligative Properties. What's the trap?

thinking the solute moves rather than the solvent.

The usual trap: thinking the solute moves rather than the solvent. How to avoid it: water moves toward the saltier side to dilute it. Go back to the definition — the net movement of solvent through a semipermeable membrane from a dilute (low-solute) side to a concentrated (high-solute) side.

Key point

Osmosis

Common mistake

thinking the solute moves rather than the solvent.

Memory tip

water moves toward the saltier side to dilute it.
