<Freezing> is a liquid-to-solid <phase transition>. A moving <phase boundary> releases <latent heat>; its rate is constrained by heat transport and the <Stefan condition>. In a solution the <liquidus> depends on composition, so being below the pure solvent's <melting> <temperature> does not imply that the solution must freeze.
