Naming Ternary Compounds Nomenclature Naming Ternary Compounds

Naming Ternary Compounds Reference Point Contain at least 3 elements Reference point begins with compounds that contain H, O, and a third non-metal These compounds are called acids

Naming Ternary Compounds Reference Point Acids are compounds formed from nonmetal elements only Examples HClO3 HNO3 H2SO4

Naming Ternary Compounds Reference Point -ic ending Reference Nonmetal- use stem of chlorine Chloric acid Acid = H HClO3

Naming Ternary Compounds Reference Point -ic ending Use a prefix- per perchloric acid Acid = H HClO4

Naming Ternary Compounds Reference Point -ous ending chlorous acid Acid = H HClO2

Naming Ternary Compounds Reference Point Use a prefix- hypo -ous ending hypochlorous acid Acid = H HClO

Naming Ternary Compounds Reference Point Name these acids (a) HBrO4 (b) HBrO3 (c) HBrO2 (d) HBrO

Naming Ternary Compounds Solutions Name these acids (a) perbromic acid (b) bromic acid (c) bromous acid (d) hypobromous acid

Naming Ternary Compounds Periodic Table Reference Point 18 13 14 15 16 17  He 3 H & 3 O 2 H & 3 O 1 H & 3 O O F Noble Gases   3 H & 4 O 2 H & 4 O

Naming Ternary Compounds Naming salts of polyatomic ions Name the metal followed by the name of the polyatomic ion Salts do not contain the hydrogen from the acid; drop the word acid from the name If the acid name ended in –ic, change it to –ate If the acid name ended in –ous, change it to -ite

Naming Ternary Compounds Examples: NaNO3 Sodium nitrate K2SO4 Potassium sulfate Al(HCO3)3 Aluminum bicarbonate or aluminum hydrogen carbonate

Polyatomic Ions A group of atoms with an overall charge. NH4+ ammonium OH- hydroxide NO3- nitrate NO2- nitrite CO32- ______________ HCO3- hydrogen carbonate (bicarbonate)

Polyatomic Compounds Match each set with the correct name: A. Na2CO3 1) magnesium sulfite MgSO3 2) magnesium sulfate MgSO4 3) sodium carbonate B. Ca(HCO3)2 1) calcium carbonate CaCO3 2) calcium phosphate Ca3(PO4)2 3) calcium bicarbonate

Solution A. Na2CO3 3) sodium carbonate MgSO3 1) magnesium sulfite MgSO4 2) magnesium sulfate B. Ca(HCO3)2 3) calcium bicarbonate CaCO3 1) calcium carbonate Ca3(PO4)2 2) calcium phosphate

Polyatomic Compounds A. aluminum nitrate 1) AlNO3 2) Al(NO)3 3) Al(NO3)3 B. copper(II) nitrate 1) CuNO3 2) Cu(NO3)2 3) Cu2(NO3) C. Iron (III) hydroxide 1) FeOH 2) Fe3OH 3) Fe(OH)3 D. Tin(IV) hydroxide 1) Sn(OH)4 2) Sn(OH)2 3) Sn4(OH)

Solution A. aluminum nitrate 3) Al(NO3)3 B. copper(II) nitrate 2) Cu(NO3)2 C. Iron (III) hydroxide 3) Fe(OH)3 D. Tin(IV) hydroxide 1) Sn(OH)4
