Ternary Ionic Date:

Ternary Ionic Cation & Anion electrostatically held together –at least one of the ions is a polyatomic ion. two or more atoms covalently bonded together with a charge – most are negative. –Polyatomic ions are listed on the back of the PT. Planning on AP chemistry? They should be memorized.

Create compounds Same as for binary ionic –Method 1 – balance e - transferred –Method 2 – LCM –Method 3 – Crossover Treat polyatomic ions as ONE unit –If you need more than one polyatomic ion, use parenthesis so subscript applies to all.

Naming Same as binary ionic –Name the cation, name the anion

Create compounds Sodium nitrate Lithium sulfate Calcium carbonate Magnesium chlorate Ammonium phosphate Potassium oxalate Barium hydroxide NaNO 3 Li 2 SO 4 CaCO 3 Mg(ClO 3 ) 2 (NH 4 ) 3 PO 4 K 2 C 2 O 4 Ba(OH) 2

Naming Ternary Ionic Mg 3 (PO 4 ) 2 Li 3 PO 3 (NH 4 ) 2 CrO 4 Al 2 (Cr 2 O 7 ) 3 Na 2 SiO 2 CaCO 3 Magnesium phosphate Lithium phosphite Ammonium chromate Aluminum dichromate Sodium silicate Calcium carbonate

Determining charge Use Algebra Fe(C 2 H 3 O 2 ) 2 CuNO 3 Pb(C 2 O 4 ) 2 WO 3
