U2_L7 Tonicity and osmolarity

Osmosis is the movement of solvent from low solute concentration to high solute concentration through a semipermeable membrane.

Osmosis is the movement of solute from high concentration to low concentration through a semipermeable membrane.

Osmosis is the movement of solvent from high solute concentration to low solute concentration through a semipermeable membrane.

Osmosis is the movement of solute from low concentration to high concentration through a semipermeable membrane.

Hypotonic solution

Isotonic solution

Hypertonic solution

Supersaturated solution

Osmolarity considers all solutes, while tonicity considers only non-penetrating solutes.

Osmolarity considers only non-penetrating solutes, while tonicity considers all solutes.

Osmolarity is not related to solute concentration, while tonicity is.

Tonicity is the total solute concentration, while osmolarity is not.
