17. Tests for Iron (II) and Iron (III) Ions
Introduction: 
Some transition metals can form cations with more than one charge.  Iron is an example of such a metal.  It forms the ferrous, or iron (II), ions which have a +2 charge.  It also forms the ferric, or iron(III), ions which have a +3 charge.  In this lab you will learn how to test a compound to determine whether it contains iron (II) or iron (III).  These tests will be useful if you need to identify and write the formula for an iron-containing compound.

18. Ternary Ionic Compounds
Formula Ions Name
Ca(NO3) Ca+2 and NO Calcium Nitrate
Ca(NO2) Ca+2 and NO Calcium Nitrite
The system does not change with multiple valence cations!

22. You’ll have to “LOOK THESE UP” until they become more familiar.
The Polyatomic Anions
ION Name
ION Name
NO Nitrate
ClO Perchlorate
NO Nitrite
ClO Chlorate
SO Sulfite
ClO Chlorite
SO Sulfate
ClO1- Hypochlorite
HSO41- Hydrogen Sulfate
(or Bisulfate)
(Still SO4-2… but reduced by H+1)
You’ll have to “LOOK THESE UP” until they become more familiar.
Don’t memorize… familiarize… decode systems & recognize patterns!!!

23. Some Polyatomic Anions You Just Can’t Find...
SeO IO IO-
Let the TABLE be your guide !!!
SO4-2 = sulfate… SeO4-2 = selenate
ClO3- = chlorate… IO3- = iodate
ClO- = hypochlorite… IO- = hypoiodite
ARE YOU WITH ME?… Which polyatomic anions are necessary for agriculture and plant reproduction?
GeO3-2 germinate and pollinate PoO4-2

24. COMPOUND EXAMPLE: NH4OH
Ionic Compound ISSUES
NOTE: the -ide ending for an anion name is reserved for “mono-element” anions with a few extremely important exceptions.
OH- = hydroxide
CN- = cyanide
O22- = peroxide
COMPOUND EXAMPLE: NH4OH
