Study Notes
Properties of Ionic Compounds
- Ionic compounds consist of vast lattices formed by alternating positive and negative ions in a regular arrangement.
- The lattice structure is maintained by strong electrostatic attractions between positively and negatively charged ions.
Common Characteristics
- High melting and boiling points due to strong ionic bonds that require significant energy to break.
- Conduct electricity when molten or in solution, as ions are free to move; they cannot conduct electricity in solid form due to fixed positions.
- Often soluble in water as water molecules can separate and stabilize ions in solution.
Definitions
- An ionic bond is the electrostatic attraction between oppositely charged ions, which creates a stable compound.
- When ionic crystals dissolve in water, they dissociate into solvated positive and negative ions.
Electrical Conductivity
- Ionic compounds conduct electricity in molten state or solution because ions are mobile; in solid state, ions are locked in place, inhibiting current flow.
Solvation
- Solvated refers to ions being surrounded and stabilized by solvent molecules, allowing for dissolution.
Charge and Attraction
- The greater the ionic charge, the stronger the attraction between ions, resulting in higher melting points for compounds with greater charges.
