OXIDESMetal oxides

They are compounds formed by a metal and oxygen, in which the oxygen has an oxidation number of –2 and the metal has a positive oxidation number.How are they formed?

Oxidation numbers are switched and written as subscripts:Fe(3+) + O(-2) → Fe2O3

If we can, we simplify:Mg(2+) + O(-2) → Mg2O2 → MgO

How do we know the oxidation number of the metal if we have the formula? The addition of the oxidation number of the two elements must be 0.

FeO: x + (-2) = 0 → x=+2→ the oxidation number of Fe is +2.Na2O→ x∙2 + (-2)=0 → x=+1 → the oxidation number of Na is +1.

How are metal oxides named? There are three different nomenclatures: Stock´s nomenclature : it is formed by two words. The first word is the name of

the metal, followed immediately by its oxidation number between brackets and in Roman numerals. If the oxidation number of the metal is invariable, it is not indicated. The second word is the word “oxide”.

FeO: iron (II) oxide óxido de hierro (II)Fe2O3: iron (III) oxideóxido de hierro (III)Na2O: sodium oxide óxido de sodio MgO: magnesium oxide óxido de magnesio

Stoichiometric nomenclature : it is formed by two words. The first word is the name of the metal with a Greek prefix that shows us the number of atoms of the metal. The second word is the word "oxide" with a Greek prefix that shows us the number of atoms of oxygen. The Greek prefixes are:1. Mono- 2. Di- 3. Tri- 4. Tetra- 5. Penta-6. Hexa- 7. Hepta- Mono- is omitted in the metal.

Na2O: disodium monoxide monóxido de disodioMgO: magnesium monoxide monóxido de magnesioFeO: iron monoxide monóxido de hierroFe2O3: diiron trioxide trióxido de dihierro

Traditional nomenclature : it is formed by two words. The first word is the root of the metal with a suffix (and sometimes also a prefix) that shows us the oxidation number of the metal. The second word is the word "oxide". The prefixes and suffixes that we use are:

-If the metal has only one oxidation number: -ic; it can be omitted.-If the metal has two oxidations numbers: -ous for the smallest one and -ic for the biggest one.-If the metal has three oxidation numbers: hypo- -ous for the smallest one, -ous for the middle one and -ic for the biggest one.-If the metal has four oxidation numbers: hypo- -ous for the smallest one, -ous for the middle smallest one, -ic for the middle biggest one and per- -ic for the biggest one.For metals we are only going to study it in Spanish.

Na2O: - óxido sódico u óxido de sodioMgO: - óxido magnésico o de magnesioFeO: - óxido ferrosoFe2O3: - óxido férrico

Non-metal oxidesThey are compounds formed by a non-metal and oxygen, in which the oxygen has an oxidation number of –2 and the non-metal has a positive oxidation number. They are named the same way as metal oxides.

Stock´s nomenclature Cl2O: chlorine (I) oxide óxido de cloro (I)Cl2O3: chlorine (III) oxide óxido de cloro (III)Cl2O5: chlorine (V) oxide óxido de cloro (V)Cl2O7: chlorine (VII) oxide óxido de cloro (VII)

Stoichiometric nomenclature Cl2O: dichlorine monoxide monóxido de dicloroCl2O3: dichlorine trioxide trióxido de dicloroCl2O5: dichlorine pentaoxide pentaóxido de dicloroCl2O7: dichlorine heptaoxide heptaóxido de dicloro

Traditional nomenclature Cl2O: hypochlorous oxide óxido hipoclorosoCl2O3: chlorous oxide óxido clorosoCl2O5: chloric oxide óxido clóricoCl2O7: perchloric oxide óxido perclórico

Exercises of metal and non metal oxides1. Write the name of the following metal and non metal oxides using all the nomenclatures we have studied:

PEROXIDESThey are formed by metals from groups 1, 2, 11 and 12 of the periodic table (which have a positive oxidation number) and ion O2

2-. In order to formulate them you can consider the ion O2

2- as a single atom with -2 as oxidation number. This way, peroxides follow the same rules as all the compounds you have studied so far (you switch the oxidation numbers and write them as subscripts and you simplify if it is necessary, but be careful, because ion O2

2- can´t be simplified). For example:K+ + O2

2- K2O2 Ba2+ + O22- Ba2(O2)2 BaO2

Stoichiometric nomenclature : you name them with the name of the metal followed by the word “oxide”. Both the name of the metal and the word “oxide” are preceded by numeral prefixes (mono-, di-, tri-, tetra-, penta-, hexa-, hepta...) which indicate their subscripts.

K2O2: potassium dioxide dióxido de dipotasioBaO2: barium dioxide dióxido de barioCu2O2: dicopper dioxide dióxido de dicobre

Stock nomenclature : they are named by the name of the metal followed by the word “peroxide”. Between the name of the metal and the word “peroxide” you have to write the oxidation number of the metal in brackets and in Roman numerals (it is omitted if it is unique).

K2O2: potassium peroxide peróxido de potasioBaO2: barium peroxide peróxido de barioCu2O2: copper (I) peroxide peróxido de cobre (I)

Traditional nomenclature : you name them with the root of the metal which has suffixes (and sometimes also prefixes) which indicate its oxidation number followed by the word “peroxide”. The prefixes and suffixes that you use are the same ones you have been using in traditional nomenclature for other compounds.

K2O2: - peróxido potásico o peróxido de potasioBaO2: - peróxido bárico o peróxido de barioCu2O2: - peróxido cuprosoA well known peroxide is hydrogen peroxide: H2O2 (agua oxigenada o peróxido de hidrógeno).3. Write the formula of the following compounds:a) calcium peroxide b) lithium peroxide c) copper (II) peroxided) copper (I) peroxide e) cadmium peroxide f) dimercury dioxide4. Name the following compounds using the three nomenclatures we have studied:a) Na2O2 b) MgO2 c) ZnO2 d) Rb2O2 e) SrO2f) Cs2O2

Metal hydridesMetal hydrides are compounds formed by a metal with a positive oxidation number and hydrogen with an oxidation number of –1.How are they named?

Stock nomenclature : we write the name of the metal followed by its oxidation number in brackets and in Roman numerals -it is omitted if it is unique-. Then, we write the word “hydride”.

FeH3: iron (III) hydride hidruro de hierro (III)FeH2: iron (II) hydride hidruro de hierro (II)LiH: lithium hydride hidruro de litio

Stoichiometric nomenclature : we write the name of the metal and the word hydride, each word preceded by a prefix (di-, tri-, tetra-, penta-...) which indicates the subscript in the formula.

FeH3: iron trihydride trihidruro de hierroFeH2: iron dihydride dihidruro de hierroLiH: lithium monohydride monohidruro de litio

Traditional nomenclature : you name them with the root of the metal using suffixes (and sometimes also prefixes) which indicate its oxidation number (the same ones as in oxides).

FeH3: - hidruro férricoFeH2: - hidruro ferrosoLiH: - hidruro lítico o hidruro de litio

Non metal hydridesThey are formed and named the same way as metal hydrides.NH3: nitrogen (III) hydride or nitrogen trihydridehidruro de nitrógeno (III) o trihidruro de nitrógenoBut, oh, wait, no one uses these names.These are the common names for these compounds:BH3 Borane Borano

Page 6: Web viewThe first word is the root of the metal with a suffix (and sometimes also a prefix) ... fluor. uro. de hidrógeno. HCl: hydrogen chloride. cloruro de hidrógeno

In this case the hydrogen has an oxidation number of +1 and the non metal has a negative oxidation number. The non metals are F, Cl, Br and I (oxidation number=-1) and S, Se and Te (oxidation number=-2)They are identified by the word “hydrogen” followed by the root of the non metal ending in -ide.

METAL-NON METAL COMPOUNDS

Page 7: Web viewThe first word is the root of the metal with a suffix (and sometimes also a prefix) ... fluor. uro. de hidrógeno. HCl: hydrogen chloride. cloruro de hidrógeno

Metal-non metal compounds (the non metal being neither O nor H)They are formed by a metal, with a positive oxidation number, and a non-metal, with a negative oxidation number.There are two rules for writing the formula of these compounds correctly:

Oxidation numbers are switched and written as subscripts.Fe(3+) + S(2-) → Fe2S3

We simplify the subscripts if we can.Fe(2+) + S(2-) → Fe2S2 → FeSNotice that non-metals usually have several oxidation numbers but only one of these oxidation numbers is negative. Therefore, in these compounds non-metals act only with one oxidation number:

F, Cl, Br, I: -1 S, Se, Te: -2 N, P, As, Sb: -3How do we name them?

Stock nomenclature : we write the name of the metal followed by its oxidation number, in brackets and in Roman numerals -it is omitted if the oxidation number is unique-. Then, we write the root of the non-metal ending in -ide.

Fe2S3: Iron (III) sulphide Sulfuro de hierro (III)FeS: Iron (II) sulphide Sulfuro de hierro (II)

Stoichiometric nomenclature : we write the name of the metal with a prefix that indicates its subscript. Then, we write the root of the non metal ending in -ide, also with a prefix that indicates its subscript.

Fe2S3: Diiron trisulphide Trisulfuro de dihierroFeS: Iron monosulphide Monosulfuro de hierro

Traditional nomenclature : we write the root of the metal with a suffix (sometimes we need also a prefix) that indicates its oxidation number. Then, we write the root of the non metal ending in -ide. The prefixes and suffixes that we use are the same as in the other compounds we have studied.

Fe2S3: - Sulfuro férricoFeS: - Sulfuro ferroso

Non metal-non metal compounds (the two non metals being neither O nor H)They are formed by a non metal with a positive oxidation number and a non metal with a negative oxidation number. The non metal with the positive oxidation number is written first.They are formed and named the same way metal-non metal compounds are formed and named.

They are formed by a metal with a positive oxidation number and the group OH-. To formulate them, you can consider that the group OH- is only one element with the oxidation number -1. This way, you just switch the oxidation numbers and write them as subscripts.The way to name them follows the same rules as in other compounds you have already studied:Compound Stock Stoichiometric TraditionalNa+ + OH- → NaOH Sodium hydroxide

OXYACIDS

Page 10: Web viewThe first word is the root of the metal with a suffix (and sometimes also a prefix) ... fluor. uro. de hidrógeno. HCl: hydrogen chloride. cloruro de hidrógeno

These are compounds with the following general formula:HaXbOc

where X is a non metal with a positive oxidation number. X can also be a transition

metal with a high oxidation number, such as Cr(+6), Mn (+4), Mn(+6) or Mn(+7).

H has an oxidation number of +1. O has an oxidation number of -2.

How do we know the oxidation number of X?To know the oxidation number of X, remember that the addition of all the oxidation numbers must be 0. For example:H2SO4: (+1)∙2 + x + (-2)∙4=0 → x=+6 → S has an oxidation number of +6How are they formed?They are obtained by adding one molecule of water to an oxide. For example, if we want to form the oxyacid of S in which it has an oxidation number of +6 we follow the following steps:

We form the oxide.S2O6 → SO3 (sulphuric oxide)

We add a molecule of water (the molecule we obtain is simplified if necessary).SO3 + H2O → H2SO4 (sulphuric acid)Let´s see another example. Let´s form the oxyacid of Cl in which this element has an oxidation number of +3:

We form the oxide: Cl2O3 (chlorous oxide) We add one molecule of water and in this case we will need to simplify:

Cl2O3 + H2O → H2Cl2O4 → HClO2 (chlorous acid)How are they named?

Root of X with suffixes and prefixes which indicate its oxidation number + “acid”The suffixes and prefixes used are:

1. If X has 1 oxidation number: -ic

2. If X has 2 oxidation numbers: -ous for the smallest one-ic for the biggest one

3. If X has 3 oxidation numbers:hypo- -ous for the smallest one-ous for the middle one-ic for the biggest one

4. If X has 4 oxidation numbers:hypo- -ous for the smallest one-ous for the middle smallest one-ic for the middle biggest oneper- -ic for the biggest one

Let´s see some examples: S has +2, +4 and +6 as oxidation numbers.

10

Page 11: Web viewThe first word is the root of the metal with a suffix (and sometimes also a prefix) ... fluor. uro. de hidrógeno. HCl: hydrogen chloride. cloruro de hidrógeno

In H2SO4, S has an oxidation number of +6 (the biggest one), so H2SO4 is sulphuric acid (ácido sulfúrico).

Cl has +1, +3, +5 and +7 as oxidation numbers.In HClO2, Cl has an oxidation number of +3 (the middle smallest one), so HClO2 is chlorous acid (ácido cloroso).

In HBrO4, Br has an oxidation number of +7 (Br has 4 oxidation numbers and +7 is the biggest one), so HBrO4 is perbromic acid (ácido perbrómico).

In HIO, I has an oxidation number of +1 (I has 4 oxidation numbers and +1 is the smallest one), so HIO is hypoiodous acid (ácido hipoyodoso).

Oxyacids: special casesOrtho- oxyacids

Page 13: Web viewThe first word is the root of the metal with a suffix (and sometimes also a prefix) ... fluor. uro. de hidrógeno. HCl: hydrogen chloride. cloruro de hidrógeno

When you name the oxyacids of P, As and Sb, you have to add 3 molecules of H2O to the oxide, not one. For example, to formulate phosphoric acid (ácido fosfórico):

P has three oxidation numbers, +1, +3 and +5. As the ending of “phosphoric” is -ic, it has +5 as its oxidation number.

You formulate the oxide: P2O5 (phosphoric oxide) You add 3 molecules of water: P2O5 + 3H2O → H6P2O8

In this case, simplifying is necessary: H6P2O8 → H3PO4.If you want to name the oxyacids of P, As and Sb in which you add only one molecule of H2O, you have to write the prefix meta-. For example:P2O5 + H2O → H2P2O6 → HPO3 metaphosphoric acid (ácido metafosfórico)In other elements (those which are not P, As and Sb), if you want to name the oxyacids in which you have added 3 molecules of H2O to the oxide, you have to write the prefix ortho-. For example, orthosulfuric acid is SO3 + 3H2O → H6SO6.

Di- oxyacidsIf you want to formulate a di- oxyacid, you multiply the oxyacid by 2 and substract 1 molecule of H2O. For example, disulphuric acid is:→ H2SO4 (sulphuric acid)→ (x2) → H4S2O8 → (-H2O) → H2S2O7

Special oxidation numbers Cr can form oxyacids using +6 as an oxidation number:

CrO3 + H2O → H2CrO4 chromic acid (ácido crómico) Mn uses only +4, +6 and +7 when it forms oxyacids, but the order of the

prefixes and suffixes change:MnO2 + H2O → H2MnO3 manganous acid (ácido manganoso)MnO3 + H2O → H2MnO4 manganic acid (ácido mangánico)Mn2O7 + H2O → H2Mn2O8 → HMnO4 permanganic acid (ácido permangánico)15. Write the formulas for the following oxyacids and oxysalts:
