REDOX REACTIONS. 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 …

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.

2. To write net ionic equations for oxidation-reduction reactions. Note: Chlorine bleach is a basic solution of sodium hypochlorite, NaOCl. When a bleach solution is acidified, hypochlorous acid, HOCl, is produced. The HOCl decomposes to gives Cl2. Both HOCl and Cl2 are oxidizing agents and may be involved in the reaction.

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.

Oxidation – Reduction Packet. Oxidation-reduction (redox) reactions are reactions in which oxidation numbers change. Oxidation numbers are either real charges or formal charges which help chemists keep track of electron transfer. In practice, oxidation numbers are best viewed as a bookkeeping device. Oxidation cannot occur without reduction.
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.
