Chapter 18 Electrochemistry is the branch of chemistry that deals with the chemical action of electricity and the production of electricity by chemical reactions. Assigning oxidation numbers: Fe O + 3CO ------- 2Fe + 3CO 2 3 2 3+ (Fe2) (These elements balance each other) (O 36- (Oxygen usually has a charge of -2. 2*3=6) (O)2- (See above) 2+ (3C) (These elements must balance each other out) 0 (2Fe) (Elemental form has no charge) (3C) 4+ (See above) (O )4- (See above) 2 Note: The electric charge is not tied to the elements stoichiometry. A useful way to check this is to remember that the sum of the oxidation states is equal to the charge of the molecule: HCO 3- H: +1 C: +4 O: -2 1(+1) + 1(+4) + 3(-2) = -1 Use this rule to predict the charges of atoms with simple math The oxidation number is the charge the atom would have in a molecule or an ionic compound if electrons were completely transferred Neutral elements have an oxidation number of zero The more electronegative element is assigned the negative charge Example: NH 3 Hydrogen is only negative when bonded with alkaline metals (column 1) H: +1 N: -3 The charges of elements are related to their position on the periodic table: Columns 1 and 2 are +1 and +2 respectively Oxygen usually has a charge of -2 Halogens (column 7) have a charge of -1 Redox reactions are those involving the oxidation and reduction of a species Oxidation and reduction must occur together The question to ask is which elements are being oxidized and which are being reduced 2Mg +O --2------- 2MgO 0 (2Mg) Magnesium is the oxidizing agent because it lost electrons (OIL) 0 (O 2 Oxygen is the reducing agent because it gained electrons (RIG) (2Mg) 2+ (O)2-
