what are the 2 rules of the classical naming system
• “ous” ending for the ion with the LOWER change -“ic” ending for the ion having the HIGHER charge
for the multivalent metal Iron (Fe) name the lower charge and the higher charge and state the charges
-Lower: Fe 2+ ferrous -Higher : Fe 3+ ferric
for the multivalent metal cobalt (Co) name the lower charge and the higher charge and state the charges
-Lower: Co 2+ cobaltous -Higher: Co 3+ cobaltic
for the multivalent metal Copper (Cu) name the lower charge and the higher charge and state the charges
-Lower: Cu + cuprous -Higher: Cu 2+ cupric
for the multivalent metal Gold (Au) name the lower charge and the higher charge and state the charges
-Lower: Au + Aurous -Higher: Au 3+ Auric
for the multivalent metal Antimony (Sb) name the lower charge and the higher charge and state the charges
-Lower: Sb 3+ Stibnous -Higher: Sb 5+ Stibnic
for the multivalent metal Tin (Sn) name the lower charge and the higher charge and state the charges
-Lower: Sn 2+ Stannous -Higher: Sn 4+ Stannic
for the multivalent metal Lead (Pb) name the lower charge and the higher charge and state the charges
-Lower: Pb 2+ plumbous -Higher: Pb 4+ plumbic

With oxyanions when you gain +1 Oxygen Atoms what is the new oxyanion name
Per_____ ate Example: Perphosphate
With oxyanions when you lose -1 Oxygen Atoms what is the new oxyanion name
____ite Example : phosphite
With oxyanions when you lose -2 Oxygen Atoms what is the new oxyanion name
hypo_____ite example: Hypophosphite
write the parent acid formulas and name them
HNO₃- nitric acid HFO₃- Fluoric acid H₂CO₃- carbonic acid H₂SO₄-sulfuric acid H₃PO₄-phosphoric acid
With oxyacids when you gain +1 Oxygen Atoms what is the new oxyacid name
Per_____ ic acid example: Perchloric acid
With oxyacids when you lose -1 Oxygen Atoms what is the new oxyacid name
_____ous acid Example: Chlorous acid
With oxyacids when you lose -2 Oxygen Atoms what is the new oxyacid name
hypo_____ ous acid Example: hypochlorous acid
With polyatomic ions when you lose -1 hydrogen what is the new polyatomic name
For carbonate and sulfate you can re write it as (bicarbonate or bisulfate) or you can just write hydrogen carbonate or hydrogen sulfate but for something like phosphate it would be dihydrogen phosphate because you still have 2 remaining hydrogens after 1 was removed. and the charges for carbonate, sulfate and phosphate turn to 1-
With polyatomic ions when you lose -2 hydrogen what is the new polyatomic name
for carbonate and sulfate they would go back to there original names because they have a charge of 2 and both those hydrogens are now gone but for phosphate it would be hydrogen phosphate. and the charges for carbonate, sulfate and phosphate turn to 2-
With polyatomic ions when you lose -3 hydrogen what is the new polyatomic name
the only polyatomic that loses 3 hydrogens is phosphate and now they would all be gone so the new name is phosphate. and the charge would be 3-
