Name to formula

  • You can click on each of these to get the answers, but try doing these on your own and then compare your answers.
  • If in doubt you may refer to the nomenclature handout, but don't make it a habit.
  • Some of these are ions so pay attention to the number and kind of charges they should have in their formula.

Formulae
  • Barium iodide hexahydrate
    BaI2     · 6H2O  Here the prefix for hydrate will denote the number of H2O molecules present.  These water molecules are associated with 1 molecule of the compound.  Don't forget the dot in the middle.
    Formula table
  • Sodium hypochlorite
    NaOCl.      Even though the formula of the hypochlorite ion is ClO-, it is written as OCl in the the formula of this compound.
    Formula table
  • Aluminum azide
    Al(N3)3.      Notice the difference between the nitride and the azide ions.
     Formula table
  • Caustic soda (Lye)
    NaOH      Notice: All 3 of these compounds are some sort of soda, but they are all chemically different and there physiological effects are vastly different from each other.  Baking soda is used as an antacid while none of the others can be ingested.
    Formula table
  • Fool's gold  (Wonder why??)
    FeS2       Iron (IV) sulfide  also known as Pyrite
