Query: Precipitation of water from aqueous mixtures with addition of
  hydrophilic ions   We examine phase separation in aqueous mixtures at fixed amounts of
hydrophilic monovalent ions. When water is the minority component, preferential
solvation can stabilize water domains enriched with ions.
  This ion-induced precipitation occurs in wide ranges of the temperature and
the average composition where the solvent would be in one-phase states without
ions. The volume fraction of such water domains is decreased to zero as the
interaction parameter $\chi$ (dependent on the temperature) is decreased toward
a critical value for each average composition.
