5 Two solutions, aluminum sulfate and potassium hydroxide, form a cloudy precipitate when mixed. When these ionic compounds are dissolved in water, the ionic bond breaks and the ions dissocate (split up). The ions are then attracted to polar water molecules. The postive ions are attracted to the negativeend (the oxygenend) of water molecules and the negative ions are attracted to positiveend (hydrogenend) of water molecules. The iondipole atractions allow the ions to remain in solution. The solutions appear clear because the ions are so small and randomly distributed in the solution.
