In an oxidation-reduction reaction like the one above, the element that is oxidized always loses electrons. The element that is reduced always gains electrons. The more general definition of redox reactions, then, involves the gain and loss of electrons rather than the gain and loss of oxygen.

Oxidation and reduction in terms of oxygen transfer Definitions. Oxidation is gain of oxygen. Reduction is loss of oxygen. For example, in the extraction of iron from its ore: Because both reduction and oxidation are going on side-by-side, this is known as a redox reaction. Oxidi. z. ing and reducing agents
OXIDATION – REDUCTION REACTIONS
This is the oxidation of a metal caused by a reaction between the metal and some substance in the environment. The best example is rusting. Corrosion is a problem for it results in the loss of structural strength of the metal. Can be prevented by coating the metal …

Oxidation Reduction Reactions- Answer Key. 4.51. If nitric acid is a strong oxidizing agent and zinc is a strong reducing agent, then zinc metal will probably reduce nitric acid when the two react; that is, N will gain electrons and the oxidation number of N must decrease.

We now understand that redox (oxidation reduction) reactions involve the transfer of electrons. Consider, for instance, the reaction between Copper ions (Cu+2(aq)) and Zinc metal (Zn(s)). The subscript (aq) on Cu+2 stands for “aqueous” and means that the ion is dissolved in water. The subscript (s) on Zn means that the Zinc metal is a solid.
