Acid-base reactions of metal ions

At the end of this activity, students should be able to:
– define acids and bases in terms of the Lewis theory
– describe the formation of aqua ions in water solution
– explain the acidity (hydrolysis) reaction of hexaaqua–metal ions
– define the products of the reactions of metal aqua ions with alkalis, ammonia and carbonates
– explain the term amphoteric hydroxides
– use the reactions of aqua complexes for the identification of metal ions.
