    Study Notes

    Chemical Nomenclature

    • Chemical Compounds are named using a systematic approach based on their chemical formula, which indicates the types of elements and their quantities in the compound, and how they are bonded.
    • Binary Compounds are formed by two elements (nonmetals) and their names are created by using the name of the first element (with a Greek prefix denoting the number of atoms of that element) and the name of the second element with the suffix "-ide".

    Naming Acids and Salts

    • Binary Acids are formed by dissolving nonmetallic hydrides in water. Their names are formed by using the prefix "hydro-", a root for the second element, and the suffix"-ic", followed by "acid".
    • Salts are ionic compounds that are formed by the reaction of an acid with a base. Their names are formed by combining the cation (positive ion) from the base and the anion (negative ion) from the acid.
    • Polyatomic Ions are groups of atoms that carry a net charge. Compounds that contain polyatomic ions are named according to the same rules as simple ionic compounds.

    Prefix System

    • Prefixes are used to indicate the number of atoms of each element.
    • Greek prefixes are used for both ionic and covalent compounds.
    • Roman numeral prefixes are used for compounds containing metals with variable valences, to indicate the oxidation state of the metal.

    Examples of Compounds and Their Names

    • Diphosphorus Pentasulfide: P2S5
    • Chlorine Trifluoride: ClF3
    • Radium Acetate: Ra(CH3COO)2
    • Iron (III) Hydroxide: Fe(OH)3
    • Silver Dichromate: Ag2Cr2O7
    • Strontium Carbonate: SrCO3
    • Lithium Bismuthate: LiBiO3
    • Sodium Tetrathionate: Na2S4O6
    • Ammonium Molybdate: (NH4)2MoO4
    • Mercury (II) Ferricyanide: Hg3[Fe(CN)6]2
    • HI (aq): Hydroiodic Acid
    • HF (aq): Hydrofluoric Acid
    • HIO (aq): Hypoiodous Acid
    • HIO2 (aq): Iodous Acid
    • HIO3 (aq): Iodic Acid
    • HIO4 (aq): Periodic Acid
    • H3AsO4 (aq): Arsenic Acid
    • H3AsO3 (aq): Arsenous Acid
    • HNO3 (aq): Nitric Acid
    • HNO2 (aq): Nitrous Acid

    Note:

    • The text provides several examples of chemical compounds and their names. Each compound is categorized based on its chemical formula and the rules for naming it.
    • Students will need to understand the different categories of compounds and the systematic rules for naming them. They will also need to be able to write the chemical formula of a compound given its name, and vice versa.

    How to Study

    • Read the text carefully, paying attention to the different naming rules.
    • Practice writing the chemical formulas for the compounds listed in thetext.
    • Practice naming the compounds given their chemical formulas.
    • Use the appendix as a resource for identifying common anions.

    Key Points for the Appendix Material

    • The appendix provides a list of common anions (negative ions) used in chemical nomenclature.
    • -1 charge anions include hydride, fluoride, chloride, bromide, iodide, cyanide, cyanate, thiocyanate, hydroxide, amide, acetate, formate, nitrate, nitrite, perchlorate, chlorate, chlorite, hypochlorite, iodate, bromate, hypobromite, permanganate, dihydrogen phosphate, hydrogen sulfate, and bicarbonate.
    • -2 charge anions include oxide, sulfide, sulfate, thiosulfate, sulfite, peroxide, hydrogen phosphate, chromate, dichromate, and carbonate.
    • -3 charge anions include nitride, phosphate, arsenate, and arsenite.
