Naming and writing formulas for ionic compounds

Naming and Writing Formulas for Ionic Compounds

9.2

  • A recipe is a formula for the sauce—a complete list of ingredients and their proportions. Chemistry also uses formulas. Once you know the rules, you can write the formula for any chemical compound.


Binary ionic compounds

9.2

Binary Ionic Compounds

  • Binary Ionic Compounds

    • How are the names of binary ionic compounds determined?

    • How do you write the formulas for binary ionic compounds?


Binary ionic compounds1

9.2

Binary Ionic Compounds

  • These masks are made of an ionic compound with the common name gypsum. This name does not tell you anything about the chemical composition of the compound, though.


Binary ionic compounds2

9.2

Binary Ionic Compounds

  • Naming Binary Ionic Compounds

    • A binary compound is composed of two elements and can be either ionic or molecular.

      • To name any binary ionic compound, place the cation name first, followed by the anion name.


Binary ionic compounds3

9.2

Binary Ionic Compounds

  • Tin(II) sulfide, or SnF2,is added to toothpastes to prevent cavities.


Binary ionic compounds4

9.2

Binary Ionic Compounds

  • Tin(IV) sulfide, or SnS2, is used in glazes for porcelain fixtures and dishes.


Binary ionic compounds5

9.2

Binary Ionic Compounds

  • Hematite, a common ore of iron, contains iron (III) oxide. The balanced formula is Fe2O3.


Binary ionic compounds6

9.2

Binary Ionic Compounds

  • Writing Formulas for Binary Ionic Compounds

    • Write the symbol of the cation and then the anion. Add whatever subscripts are needed to balance the charges.

Compounds With Polyatomic Ions

  • Compounds with Polyatomic Ions

    • How do you write the formulas and names of compounds containing polyatomic ions?


Compounds with polyatomic ions1

9.2

Compounds With Polyatomic Ions

  • Write the symbol for the cation followed by the formula for the polyatomic ion and balance the charges.


Compounds with polyatomic ions2

9.2

Compounds With Polyatomic Ions

  • For example, calcium nitrate is composed of a calcium cation (Ca2+) and a polyatomic nitrate anion (NO3–).

  • In calcium nitrate, two nitrate anions, each with a 1– charge, are needed to balance the 2+ charge of each calcium cation. The formula for calcium nitrate is Ca(NO3)2.

Compounds With Polyatomic Ions

  • Naming Compounds with Polyatomic Ions

    • To name a compound containing a polyatomic ion, state the cation first and then the anion, just as you did in naming binary ionic compounds.

Compounds With Polyatomic Ions

  • Sodium hypochlorite (NaClO) is used as a disinfectant for swimming pools. The metallic cation in this compound is sodium (Na+) so the polyatomic ion must be ClO–.
