Oxidising Agents and Reduction Agents In a redox reaction, a compound that is reduced is the oxidizing agent. An oxidising agent is a substance which oxidises something else. Inversely, a compound that is oxidised is the reducing agent. A reducing agent reduces something else. Example: In this reaction, iron(III) oxide is reduced. Therefore it is … Read more
Oxidation and Reduction in Terms of Electron Transfer Oxidation occurs when a reactant loses electron. Reduction occurs when a reactant gain of electron. Example: CuO + Mg → Cu + MgOIn this reaction, copper (II) ion in copper(II) oxide gains 2 electrons to form copper metal.Half equation:Cu2+ + 2e → Cu This is a reduction process. Magnesium metal … Read more
Oxidation and Reduction in Term of Changes of Oxidation State Oxidation involves an increase in oxidation stateReduction involves a decrease in oxidation state Another way to determine oxidation and reduction is to see the change of the oxidation state after a reaction. An atom is said to be oxidised when its oxidation state increases. An … Read more
Using the Oxidation States in Naming Compounds You will have come across names like iron(II) sulphate and iron(III) chloride. The (II) and (III) are the oxidation states of the iron in the two compounds: +2 and +3 respectively. That tells you that they contain Fe2+ and Fe3+ ions. Example Formula Name of the compound FeCl2 … Read more
Oxidation States (Oxidation Numbers) Oxidation state shows the total number of electrons which have been removed from an element (a positive oxidation state) or added to an element (a negative oxidation state) to get to its present state. Oxidation State of Some Elements 1. The oxidation state of an element is zero.Example Element Oxidation State … Read more
Oxidation and Reduction in Terms of Hydrogen Transfer Oxidation is the process of losing hydrogen. Reduction is the process of gaining hydrogen. For example, ethanol can be oxidised to ethanal: Ammonia loses hydrogen. Ammonia is oxidised to become nitrogen. This is an oxidation process. Bromine gains hydrogen. Bromine is reduced to become hydrogen bromide. This is a reduction process. … Read more
Oxidation and Reduction in Terms of Oxygen Transfer Oxidation is the process of gaining oxygen. Reduction is the process of losing oxygen. For example, in the extraction of iron from its ore: Iron(III) oxide loses oxygen. Iron(III) oxide is reduced to iron. This is a reduction process. Carbon monoxide gains oxygen. Carbon monoxide is oxidised … Read more
A redox reaction is a chemical reaction that involves reduction and oxidation that occurs simultaneously. In a redox reaction, both reduction and oxidation are going on side-by-side. Oxidation and reduction can be defined in terms of loss or gain of oxygen loss or gain of hydrogen transfer of electrons change in oxidation number The redox … Read more
Understanding Oxidation and Reduction Oxidation and reduction can be understood from the aspect of: Losing or gaining oxygen Losing or gaining hydrogen Transferring of electron Changing of oxidation number
