    Study Notes

    Inorganic Chemistry

    Definition and Scope

    • Branch of chemistry that deals with the study of inorganic compounds, which are typically derived from mineral sources
    • Involves the study of the properties, preparation, and reactions of inorganic compounds

    Types of Inorganic Compounds

    • Acids: compounds that donate H+ ions (e.g. HCl, H2SO4)
    • Bases: compounds that accept H+ ions (e.g. NaOH, Ca(OH)2)
    • Salts: ionic compounds formed from the reaction of acids and bases (e.g. NaCl, CaCO3)
    • Oxides: compounds containing oxygen and another element (e.g. CO2, Fe2O3)
    • Atomic Radius: decreases from left to right across a period, increases down a group
    • Electronegativity: increases from left to right across a period, decreases down a group
    • Ionization Energy: increases from left to right across a period, decreases down a group

    Main Group Elements

    • Alkali Metals (Group 1): highly reactive, lose one electron to form a +1 ion (e.g. Li, Na, K)
    • Alkaline Earth Metals (Group 2): less reactive, lose two electrons to form a +2 ion (e.g. Mg, Ca, Sr)
    • Halogens (Group 17): highly reactive, gain one electron to form a -1 ion (e.g. F, Cl, Br)
    • Noble Gases (Group 18): unreactive, do not easily form ions (e.g. He, Ne, Ar)

    Transition Metals

    • Characteristics: exhibit multiple oxidation states, form colored ions, and are often used as catalysts
    • Examples: Fe, Cu, Zn, Ag, Au

    Coordination Compounds

    • Definition: complexes formed between a central metal atom and surrounding ligands
    • Nomenclature: use prefixes to indicate the number of ligands and the metal's oxidation state
    • Examples: [Fe(H2O)6]3+, [Cu(NH3)4]2+

    Acid-Base Chemistry

    • Arrhenius Theory: acids donate H+ ions, bases accept H+ ions
    • Brønsted-Lowry Theory: acids donate H+ ions, bases accept H+ ions, and conjugate acid-base pairs form
    • pH: a measure of the concentration of H+ ions, with a pH of 7 being neutral
