Oxidation is a reaction that removes an electron from a substance; reduction is a reaction that adds electrons to a substance.<\/p>\n\n\n\n<p><strong>Complete Explanation<\/strong><\/p>\n\n\n\n<p>Oxidation is the loss of electrons, while reduction is the gain of electrons; a duality that forms the core of redox reactions. Remember the mnemonic OIL RIG (Oxidation Is Loss, Reduction Is Gain)! But these processes aren\u2019t just about electrons; they also involve changes in oxidation states and are inseparable in chemical reactions.&nbsp;<\/p>\n\n\n\n<p><strong>In simple terms:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Oxidation = losing electrons<\/li>\n\n\n\n<li>Reduction = gaining electrons<\/li>\n<\/ul>\n\n\n\n<p>An easy way to remember this is the phrase OIL RIG: Oxidation Is Loss, Reduction Is Gain (of electrons).<\/p>\n\n\n\n<p>So, when a substance loses electrons, it is being oxidized.<\/p>\n\n\n\n<p>When a substance gains electrons, it is being reduced.<\/p>\n\n\n\n<h2 id=\"electron-transfer-is-the-heart-of-oxidation-and-reduction\" class=\"wp-block-heading\">Electron Transfer is the Heart of Oxidation and Reduction<\/h2>\n\n\n\n<p>At the atomic level, oxidation and reduction are all about electrons:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Oxidation:<\/strong> When a substance loses electrons <br>(e.g., iron rusting: Fe \u2192 Fe\u00b3\u207a + 3e\u207b).<\/li>\n\n\n\n<li><strong>Reduction:<\/strong> When a substance gains electrons <br>(e.g., oxygen in rusting: O\u2082 + 4e\u207b \u2192 2O\u00b2\u207b).<\/li>\n<\/ul>\n\n\n\n<p>These processes always occur together, like a seesaw. If one molecule loses electrons (oxidation), another must gain them (reduction).<\/p>\n\n\n\n<h2 id=\"oxidation-states\" class=\"wp-block-heading\">Oxidation States<\/h2>\n\n\n\n<p><strong>Oxidation states<\/strong> (or oxidation numbers) help track electron movement:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Oxidation<\/strong> increases the oxidation state (e.g., Fe from 0 to +3).<\/li>\n\n\n\n<li><strong>Reduction<\/strong> decreases the oxidation state (e.g., O from 0 to -2).<\/li>\n<\/ul>\n\n\n\n<p>For example, in the reaction 2Mg + O\u2082 \u2192 2MgO:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Magnesium\u2019s oxidation state rises from 0 to +2 (oxidized).<\/li>\n\n\n\n<li>Oxygen\u2019s oxidation state drops from 0 to -2 (reduced).<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Real-World Examples<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rusting of Iron:<\/strong> Iron loses electrons (oxidation), while oxygen gains them (reduction).<\/li>\n\n\n\n<li><strong>Combustion:<\/strong> Burning methane (CH\u2084 + 2O\u2082 \u2192 CO\u2082 + 2H\u2082O) involves carbon losing electrons (oxidation) and oxygen gaining them (reduction).<\/li>\n\n\n\n<li><strong>Batteries:<\/strong> In a lithium-ion battery, lithium atoms lose electrons (oxidation) during discharge, while cobalt oxide gains them (reduction).<\/li>\n<\/ul>\n\n\n\n<h2 id=\"oxidizing-vs-reducing-agents\" class=\"wp-block-heading\">Oxidizing vs. Reducing Agents<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Oxidizing agents accept electrons and get reduced (e.g., O\u2082, KMnO\u2084).<\/li>\n\n\n\n<li>Reducing agents donate electrons and get oxidized (e.g., Na, H\u2082).<\/li>\n<\/ul>\n\n\n\n<p>In the reaction Zn + Cu\u00b2\u207a \u2192 Zn\u00b2\u207a + Cu:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Zinc (reducing agent) loses electrons.<\/li>\n\n\n\n<li>Copper ions (oxidizing agent) gain electrons.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-align-center has-vivid-red-color has-text-color has-link-color has-medium-font-size wp-elements-57653bb9a8af4e3a48437058596759f5\"><strong>Common Doubts in Chemistry<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/write-down-the-name-of-the-functional-group-of-cho\/\"><strong>Write Down the Name of the Functional Group of \u2013CHO<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/molecular-mass-of-benzene-is\/\"><strong>Molecular mass of Benzene is ___g\/mol<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/1-ton-is-equal-to-how-many-kg\/\"><strong>1 Ton is Equal to How Many Kg?<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/parsec-is-the-unit-of-which-physical-quantity\/\"><strong>Parsec is the Unit of Which Physical Quantity?<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-is-the-molecular-weight-of-naoh\/\"><strong>What is the Molecular Weight of NaOH?<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/one-metric-ton-is-equal-to\/\"><strong>One Metric Ton is Equal to&nbsp;<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/correct-the-following-1m-1000-cm\/\"><strong>Correct the following: 1m=1000 cm<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/how-do-you-determine-the-mass-of-potassium-in-33-5-g-of-kcl\/\"><strong>How do you determine the mass of potassium in 33.5 g of KCl?<\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"The correct answer is: A.
