Criss Cross Method for writing the formula for an ionic compound given its name
Criss-cross method involves bringing the valency (charge) of one element down as a subscript next to the other element or polyatomic ion.
•Practice writing the formula of the following compounds by using the criss-cross method.

Naming the Acids

Naming of Complex Compounds
• Please go back to Ch 2 in the ibook for details on the naming of the complexes or coordination compounds.
Name cation first followed by anion. Within a complex, transition metal is named first with its charge listed within parenthesis, followed by ligands and then anion. If complex is anion, then its name ends in –ate.

Naming of the Hydrates
• Hydrates are ionic compounds that have loosely attached water molecules to them. Ex. CuSO4. 5H2O.
• To name the hydrates, name the ionic compound first and then use the prefix that indicates the number of water molecules attached.
• Ex. The name of CuSO4.5H2O is Cupric Sulfate pentahydrate or Copper (II) Sulfate pentahydrate.
