Melting point depression<br />
(a) (b)<br />
◮ without salt: dynamic equilibrium (a) at <strong>melting</strong> point<br />
◮ with salt (i.e. NaCl): disruption <strong>of</strong> equilibrium (b)<br />
◮ foreign molecules (i.e. Na + , Cl − ) dissolve in the water<br />
◮ the chemical potential <strong>of</strong> the solvent is decreased by dilution<br />
◮ equilibrium between solid <strong>and</strong> liquid phase is established at<br />
another depressed <strong>melting</strong> point<br />
