Linear Relation between T_H (Homogeneous Ice Nucleation Temperature) and T_m (Melting Temperature) for Several Aqueous Solutions(Papers presented at the 53rd Annual Meeting)

Abstract

Homogeneous ice nucleation (T_H) and melting (T_m) temperatures were measured for emulsified aqueous solutions of NaCl, methanol, and (CH_3)_4NCl as a function of solute concentration. There is a linear relation between T_H and T_m for aqueous NaCl and (CH_3)_4NCl solutions, but not for aqueous methanol solution. Qualitative interpretation is given for the non-linear relation between T_H and T_m for aqueous methanol solution.
