WebSep 1, 2016 · Ionic redistribution. Migration of ions on freezing. 1. Introduction. In winter, when oceans freeze up (usually at −1.9 °C), the ice at the top contains much less salt than water underneath the surface. This is because of the buildup of ice crystals by pure water leaving the dissolved salts in liquid phase. The self-ionization of water was first proposed in 1884 by Svante Arrhenius as part of the theory of ionic dissociation which he proposed to explain the conductivity of electrolytes including water. Arrhenius wrote the self-ionization as . At that time, nothing was yet known of atomic structure or subatomic particles, so he had no reason to consider the formation of an ion from a hydrogen atom on electrolysis as any less likely than, say, the formation of a ion from a sodium atom.
