Nomenclature Name-to-Formula Solutions

The key to solving these correctly is knowing the charges on the ions and correctly placing them together. For example, in Problem 1, aluminum has a +3 charge while fluoride has a -1 charge. To make the charges balance, we must have three fluorides for every aluminum. The other problems follow the same logic. Problems 12 and 13 are acids so they must be dealt with in a slightly different way.

  1. aluminum fluroide: AlF3
  2. carbon tetracloride: CCl4
  3. strontium nitrate: Sr(NO3)2
  4. sodium bisulfate: Na HSO4
  5. iron (III) oxide: Fe2O3
  6. mercury (II) nitrate: Hg(NO3)2
  7. sodium sulfite: Na2SO3
  8. ammonium dichromate: (NH4)2Cr2O7
  9. magnesium acetate: Mg(C2H3O2)2
  10. zinc hydroxide: Zn(OH)2
  11. nitric acid: HNO3
  12. hypochlorous acid: HClO
  13. phosphoric acid: H3PO4
  14. aluminum nitrate: Al(NO3)3
