- Ionic substances in solution
- Many ionic substances dissolve in water without difficulty.
- As they dissolve, the ions become surrounded by water molecules and they spead throughout the solution.
- The hydrated ions are randomly arranged and behave independently.
- Water surrounds ions in the way that it does because it is a polar molecule with a bent shape.
- The positive hydrogen atoms in water are attracted to negative ions.
- Water molecules surround positive ions with the oxygen atoms pointing inwards.
- Each ion is surrounded by its own sphere of water molecules- this process is known as hydration.
