A redox reaction occurs when a certain substance is oxidized, while another is reduced. During oxidation, the substance loses one or more electrons, and thus becomes positively charged. Conversely, during reduction, the …Chemical reactions in which electrons are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.The balanced reduction half reaction is as follows: 2H+ + 2e− → H2 (11.5.5) (11.5.5) 2 H + + 2 e − → H 2. There are two hydrogen atoms on each side, and the two electrons written as reactants serve to neutralize the 2+ charge on the reactant hydrogen ions. Again, the overall charge on both sides is zero.

Most chemical reactions can be classified into one or more of five basic types: acid–base reactions, exchange reactions, condensation reactions (and the reverse, cleavage reactions), and oxidation–reduction reactions. The general forms of these five kinds of reactions are summarized in Table 7.10.1, along with examples of each.Therefore, a reduction is a chemical reaction in which a compound gains electrons. Here's an example to better illustrate this: CH 4 + 2O2 → CO2 +2H 2O. Let's assign oxidation numbers ( ON) for every atom (I will not go into the rules for doing this here) C−4H +1 4 + 2O0 2 → C+4O−2 2 + 2H +1 2 O−2.A combustion reaction is an exothermic redox chemical reaction where a fuel reacts with oxygen to produce gaseous products. Although it is usually initiated by a form of energy, such as using a lit match to light a fire, the released heat provide energy for sustaining the reaction.
