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.
TernaryIonic Compounds FormulaIonsName Ca(NO3)2 Ca+2 and NO31- Calcium Nitrate Ca(NO2)2 Ca+2 and NO21- Calcium Nitrite The system does not change with multiple valence cations! Fe(NO3)2 Fe2+ and NO31- Iron (II)Nitrateor FerrousNitrate

ThePolyatomicAnions IONName IONName NO31- Nitrate ClO41- Perchlorate NO21- Nitrite ClO31- Chlorate SO32- Sulfite ClO21- Chlorite SO42- Sulfate ClO1- Hypochlorite HSO41- HydrogenSulfate (orBisulfate) (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!!!
Some Polyatomic Anions You Just Can’t Find... SeO4-2IO3-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
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
ACID NOMENCLATURE How do you know a formula is that of an ACID? Starts with “H” What 2 types of ACID formulas will we name? BINARY: HCl, H2S, H3N… TERTIARY: HClO3, H2SO4, HNO3…
ACID NOMENCLATURE TERNARY(oxyacids) H __ __ __ … BINARY H __ “Hydro” ______ic Acid “-ate groups” form “-ic acids” “-ite groups form - -“ous acids” HCl Hydrochloric Acid HNO3 contains nitrate Nitric acid HNO2 contains nitrite Nitrous acid H2S Hydrosulfuric Acid
WRITE FORMULAS:hydrosulfuric acidhydrofluoric acidbromic acidbromous acidhypobromous acid
This lab activity requires mixing ionic compounds, determining AND naming products… and writing equations to represent the formation of each precipitate
