Document Summary
Dilution the lowering of the concentration of a solution. What you have before the dilution takes place. Oxidation/reduction reactions in which electrons are transferred from one reaction to another. Oxidation is when it loses an electron and becomes a more positively charged product. Reduction is when it gains an electron and becomes a more negatively charged product. Oxidation numbers how we track the electrons that are transferred from one reactant to another. Oxidation rules: for atoms in it"s elemental form the oxidation number is always zero, for monatomic ions the oxidation number equals the ionic charge, for non metals, oxidation number of oxygen in both ionic and molecular compounds. Other halogens (cl, br, i) have an oxidation number of -1 in most binary compounds. When combined in oxyanions they have positive oxidation numbers: the sume of the oxidation numbers of all the atoms in a neutral compound is zero.
