Key Concepts

Lattice Energy

Lattice energy is the energy required to break the ionic lattice apart into individual ions. A high lattice energy can make an ionic compound less likely to dissolve in water, because more energy is needed to overcome the forces holding the lattice together.

Ionic Compounds

Ionic compounds are formed from positive and negative ions held together by strong electrostatic forces. Their structure typically consists of a crystalline lattice, and whether they dissolve in water depends on the balance between the lattice forces and the interactions with the solvent.

General Solubility Rules

General solubility rules are empirical guidelines that predict the solubility of ionic compounds in water. They help determine which salts are likely to be soluble, such as many alkali metal and nitrate salts, and which might be insoluble, based on common patterns observed in chemical behavior.

Hydration Energy

Hydration energy is the energy released when water molecules surround and interact with the ions of an ionic compound. When the hydration energy exceeds the lattice energy, the compound is more likely to dissolve, as the process becomes energetically favorable.

Ion?Dipole Interactions

Ion?dipole interactions occur between the charged ions of an ionic compound and the polar water molecules. These interactions are key to the dissolution process, as they help to stabilize the ions in solution and drive the compound to dissociate in water.
