A reaction in which electrons are transferred from one atom to another is called an oxidation–reduction reaction. For simplicity, chemists often refer to oxidation–reduction reactions as redox reactions. OXIDATION NUMBERS. Oxidation numbers refer to the charge value of an element in a compound. They are used to keep track of electrons.

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 …

Oxidation-Reduction Reactions - Chemistry LibreTexts
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.

OXIDATION – REDUCTION REACTIONS
A half reaction shows either the oxidation or reduction portion of a redox equation including if the electrons are gained or lost. A reduction half reaction shows an atom or ion gaining one of more e-:Fe3+ + 3e- FeNotice that the e- is on the left.

OXIDATION – REDUCTION . REACTIONS. OXIDATION. is the process by which a substance loses one or more electrons. It was first used to describe reactions in which oxygen was added to a reactant. 4 Fe + 3 O2 ( 2 Fe2 O3. REDUCTION. is the process by which a substance gains one or more electrons. It first meant the removal of oxygen from a compound.

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.
