In this reaction, hydrogen sulphide \(\left( {{{\rm{H}}_{\rm{2}}}{\rm{S}}} \right)\) has given hydrogen and thereby reduced to sulphur by oxidation. \({\rm{2Mg + }}{{\rm{O}}_{\rm{2}}} \to {\rm{2MgO}}\) (Oxidation of \({\rm{Mg}}\) to \({\rm{MgO}}\)), The removal of oxygen from a substance is known as reduction. Oxidation: the gaining of oxygen atoms is termed as oxidation. Step 1: Look for soluble reactants reacting to create one or more insoluble products. Electrons are gained. For example, rust is formed when there is an oxidation-reduction reaction between oxygen contained in water or moist air (an oxidizing substance) and iron (a reducing substance). Some of the common examples of oxidation reactions observed are: Respiration is an oxidation reaction that takes place in our body. In the above example reduction occurs by loss of oxygen. One can identify reduction by checking the oxidation number of the elements; if the oxidation number decreases, reduction occurs in the reaction. Addition of oxygen: C + O2 CO2 (oxidation of carbon) 2. Reducing agent is an element that takes oxygen for Oxford reduction or gives hydrogen to the other elements, or it receives electrons in the process of reduction. Here Fe from Fe, Is converted To F e and see from CO Is converted to CO. . An electrode is a good source of conducting electricity as it is a solid conductor, in other words we can use Anode and Cathode. The oxidized species loses electrons, while the reduced species gains electrons. Hydrogen and oxygen have oxidation numbers of +1 and -2. On the other hand, carbon (C) has gained oxygen and converted to carbon monoxide by oxidation. Ans. The basic definition can be defined as: One reactant is oxidized (loses electrons), while another is reduced (gains electrons). Oxidation and reduction are either defined in terms of the addition/removal of oxygen and hydrogen or in terms of gain/loss of electrons. In this example, the iron(III) oxide Is an oxidising agent, whereas carbon monoxide oxide is the reducing agent. Finally, we answered some frequently asked questions on this topic. .
