2. Anion hydration.
3. Cation hydration.
4. Cations and anions that have been dissolved start to settle as a solid salt.
5. The rate of dissolution and recrystallization are equal.
Without hydration of the ions, the cation and anion cannot get separated. The three processes of ion dissociation, cation hydration, and anion hydration must all take place at once.
