The reducing agent is a substance that causes reduction by losing electrons; therefore its oxidation state increases.

The reaction below is a redox reaction that produces zinc sulfide: Zn + S → ZnS. The reducing agent donates electrons, meaning that the reducing agent itself is oxidized. These compounds are strong oxidizing agents because elements become more electronegative as the oxidation states of their atoms increase. Oxidizing Agent: An oxidizing agent is a substance that can be reduced by obtaining electrons. All you need to do is write the oxidation numbers of each element or ion in each compound and see which reactant has an element with an oxidation number that increased or decreased . Oxidizing agents removes electrons from another substance in a redox reaction whereas reducing agents donates electrons. Oxidizing and reducing agents are especially crucial in biological processes such as metabolism and photosynthesis. The nickel-cadmium (nicad) battery, a rechargeable “dry cell” used in battery-operated devices, uses the following redox reaction to generate electricity: Cd(s) + NiO. Redox reactions involve both reduction and oxidation taking place. If you liked this video, please subscribe to my channel by clicking on the YouTube button! Difference Between Reducing Agent and Oxidizing Agent Definition. Therefore, oxidizing agents oxidizes other substances and reducing agents reduces them. Or. Metals act as reducing agents in their chemical reactions. Reducing agents donate electrons while oxidising agents gain electrons. Oxidizing Agent: The oxidation state of oxidizing agent decreases.

During a reaction, oxidizing agent undergoes reduction. Electron acceptors participate in electron-transfer reactions.In this context, the oxidizing agent is called an electron acceptor and the reducing agent is called an electron donor. How do you determine the oxidizing and reducing agents in an equation? Oxidation State. The simplest way to think of this is that the oxidizing agent is the substance that is reduced, while the reducing agent is the substance that is oxidized as shown in Figure \(\PageIndex{1}\) and summarized in Table \(\PageIndex{1}\). Good reducing agents include the active metals, such as sodium, magnesium, aluminum, and zinc, which have relatively small ionization energies and low electro-negativities. Both have various applications in chemistry. Oxidizing and Reducing Agents. Reducing Agent: A reducing agent is a substance that can be oxidized by losing some of its electrons.

Oxidising and Reducing Agents (1) Definition: The substance (atom, ion or molecule) that gains electrons and is thereby reduced to a low valency state is called an oxidising agent, while the substance that loses electrons and is thereby oxidised to a higher valency state is called a reducing agent. 2 (s) + 2 H. 2. Sample Exercise 20.1 Identifying Oxidizing and Reducing Agents. For example, organisms use electron acceptors such as NAD The half-reactions can be written: Oxidation: Zn → Zn 2 + + 2 e − Reduction: S + 2 e − → S 2 − In the reaction above, the zinc is being oxidized by losing electrons. Oxidizing Agent vs Reducing Agent.
