Chapter 6 Ionic and Molecular Compounds 6.4 Polyatomic Ions Learning Goal Write the name and formula for an ionic compound containing a polyatomic ion.

Polyatomic Ions A polyatomic ion is a group of atoms with an overall ionic charge. NH4+ ammonium OH− hydroxide NO3− nitrate NO2− nitrite CO32− carbonate PO43− phosphate HCO3− hydrogen carbonate (or bicarbonate)

Polyatomic Ions Figure 6.3 Many products contain polyatomic ions, which are groups of atoms that have an ionic charge.

Naming Polyatomic Ions The names of the common polyatomic anions end in ate NO3− nitrate PO43− phosphate with one oxygen less end in ite NO2− nitrite PO33− phosphite with hydrogen use prefix hydrogen (or bi) HCO3− hydrogen carbonate (bicarbonate) HSO3− hydrogen sulfite (bisulfite)

Names and Formulas of Common Polyatomic Ions

Names and Formulas of Common Polyatomic Ions

Writing Formulas for Compounds with Polyatomic Ions To write the correct formula for compounds containing polyatomic ions, first determine the ratio of ions using charge balance. Write the formula for calcium nitrate. 1. The total negative and positive charges must equal zero

Writing Formulas for Compounds with Polyatomic Ions 2. When more than one polyatomic ion is needed for charge balance, the subscript is written outside the closing parenthesis of the polyatomic ion. Ca2+ + 2 NO3−  Ca(NO3)2 Calcium ion + 2 Nitrate ions Calcium nitrate

Guide to Writing Formulas with Polyatomic Ions

Learning Check Write the formula for aluminum bicarbonate.

Solution Write the formula for aluminum bicarbonate. Step 1 Identify the cation and polyatomic ion (anion). Cation Polyatomic Ion (anion) Al3+ HCO3−

Solution Write the formula for aluminum bicarbonate. Step 2 Balance the charges.

Solution Write the formula for aluminum bicarbonate. Step 3 Write the formula, cation first, using the subscripts from the charge balance. Al3+ + 3 HCO3−  Al(HCO3)3 Aluminum + 3 Bicarbonate ions Aluminum bicarbonate

Naming Ionic Compounds with Polyatomic Ions When naming ionic compounds containing polyatomic ions, write the name of the positive ion, usually a metal first write the name of the polyatomic ion last Learn to recognize polyatomic ions in ionic compound names and formulas.
