- When an ionic compound dissolves in water
- Ions dissociate
- Ions are surrounded by water molecules
- These ions are said to be hydrated
- They are represented by
- Mn+
- Xy-
- Water molecules orient themselves so that
- Their positively charged end (the hydrogen’s) faces the anions
- Their negatively charged end (The oxygen) faces the cations
- This process is hydration
- Many cations are surrounded by a fixed number of tightly bound water molecules
- g Fe3+ is surrounded by six water molecules and becomes [Fe(H2O)6]3+
- The charge on the complex remains unchanged
