  2. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    Oxidation numbers are fundamental to the chemical nomenclature of ionic compounds. For example, Cu compounds with Cu oxidation state +2 are call cupric and those with state +1 are cuprous. [4]: 172 The oxidation numbers of elements allow predictions of chemical formula and reactions, especially oxidation-reduction reactions. The oxidation ...

  3. Half-reaction - Wikipedia

    en.wikipedia.org/wiki/Half-reaction

    Note the transfer of electrons from Fe to Cl. Decomposition is also a way to simplify the balancing of a chemical equation. A chemist can atom balance and charge balance one piece of an equation at a time. For example: Fe 2+ → Fe 3+ + e − becomes 2Fe 2+ → 2Fe 3+ + 2e −; is added to Cl 2 + 2e − → 2Cl −; and finally becomes Cl 2 ...

  4. IUPAC nomenclature of inorganic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    When the metal has more than one possible ionic charge or oxidation number the name becomes ambiguous. In these cases the oxidation number (the same as the charge) of the metal ion is represented by a Roman numeral in parentheses immediately following the metal ion name. For example, in uranium(VI) fluoride the oxidation number of uranium is 6 ...

  5. Oxygen balance - Wikipedia

    en.wikipedia.org/wiki/Oxygen_balance

    A molecule is said to have a positive oxygen balance if it contains more oxygen than is needed and a negative oxygen balance if it contains less oxygen than is needed. [2] An explosive with a negative oxygen balance will lead to incomplete combustion, which commonly produces carbon monoxide, which is a toxic gas. Explosives with negative or ...

  6. List of chemistry mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.

  7. Organic redox reaction - Wikipedia

    en.wikipedia.org/wiki/Organic_redox_reaction

    Organic redox reactions: the Birch reduction. Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds.In organic chemistry oxidations and reductions are different from ordinary redox reactions, because many reactions carry the name but do not actually involve electron transfer. [1]

  8. Oxide - Wikipedia

    en.wikipedia.org/wiki/Oxide

    An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound containing at least one oxygen atom and one other element [1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O 2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials ...

  9. Disproportionation - Wikipedia

    en.wikipedia.org/wiki/Disproportionation

    The chlorine reactant is in oxidation state 0. In the products, the chlorine in the Cl − ion has an oxidation number of −1, having been reduced, whereas the oxidation number of the chlorine in the ClO − 3 ion is +5, indicating that it has been oxidized. Decomposition of numerous interhalogen compounds involve disproportionation.
