Abstract
An experimental method has been devised to determine the effect of water‐soluble substances on the supercooling of pure water. It was found that solutes influence the supercooling of water in a systematic manner. The nonequilibrium freezing‐point depression of a solution (Δt)f varied with the type of solute and, for a particular solute, increased with increasing solute concentration. The depression (Δt)f could be related to the equilibrium freezing point depression of the solution (Δt)e, the supercooling of water (Δt)w and a supercooling increment δ which depended on the type of solute. Some relations between the experimental results and the structure of aqueous solutions are discussed.
