  2. 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 ...

  3. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    The number indicates the degree of oxidation of each element caused by molecular bonding. In ionic molecules, the oxidation numbers are the same as the element's ionic charge. Thus for KCl, potassium is assigned +1 and chlorine is assigned -1. [4] The complete set of rules for assigning oxidation numbers are discussed in the following sections.

  4. 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.

  5. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    One example is that someone can use the charge of an ion to find the oxidation number of a monatomic ion. For example, the oxidation number of + is +1. This helps when trying to solve oxidation questions. A charge number also can help when drawing Lewis dot structures. For example, if the structure is an ion, the charge will be included outside ...

    [1] [2] The adjacent oxidation states, however, will favor comproportionation if the middle oxidation state is in the “bottom of a valley”. [2] By Jensen's inequality , drawing the line between the oxidation state to the left and the one to the right and seeing if the species lies above or below this line is a quick way to determine ...

  8. 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]

  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.
