Lesson 1: Solubility
Dissociation
-
-
For dissociation to take place the attraction between the ions and the solvent molecule must overcome the electrostatic forces of attraction between the ions in the ionic solid.
Hydration enthalpy is the of energy released when attractions are set up between cations or anions and solvent molecules
Hydration
With positive ions, there may be only intermolecular forces of attraction between the slightly negative oxygen atoms in water molecules and the positive ions or there may be formal dative covalent bonds.
-
-
With negative ions, hydrogen bonds are formed between lone pairs of electrons on the negative ions and the slightly positive hydrogens in water.

Conductivity
Electrolytic Solutions
-
-
Ionic solutions possess the ability to conduct electricity, due to the presence of mobile ions which can carry and electrical charge.
