  1. Chemical Nomenclature calcium carbonate CaCO3 CO32- carbonate Naming Complex Ionic Compounds • contain polyatomic ions

  2. Mnemonic NICK the NO3-or nitrate CAMEL had a CO32-or carbonate CLAM for ClO3- or chlorate SUPPER in SO42- or sulfate PHOENIX PO43-orphosphate Hi, I’m Nick Name the polyatomic ion: NaNO3 NO3-or nitrate NaHCO3 HCO3-or hydrogen carbonate NaOH OH-or hydroxide

  3. Examples: Na2SO4 Ba (ClO)2 NH4NO3 The Rules– formula to name 1. Write down name of + ion. 2. Write down name of – ion. sodium sulfate barium hypochlorite ammonium nitrate

  4. Examples: potassium phosphate K3PO4 sodium acetate NaCH3COO magnesium hydroxide Mg(OH)2 Name to formula - The Rules 1. Write down symbol & charge of + ion. 2. Write down symbol & charge of – ion. 3. Balance # of each ion until net charge = zero. K+ PO43- 3 of these 1 of these Na+ CH3COO- 1 of these 1 of these Mg2+ OH- 1 of these 2 of these

  5. Ticket out of Class KMnO4 - name? Magnesium nitrite - formula? … and why? References: McGraw-Hill Ryerson. 2001. Chemistry 11. Toronto.
