A redox reaction is a chemical reaction involving both reduction and oxidation processes occurring simultaneously.Key concepts:- Oxidation: Loss of electrons- Reduction: Gain of electrons- Oxidizing agent: Accepts electrons (gets reduced)- Reducing agent: Donates electrons (gets oxidized)Memorization trick: OIL RIG- Oxidation Is Loss of electrons- Reduction Is Gain of electronsExample 1: Rusting of iron4Fe + 3O₂ → 2Fe₂O₃- Iron loses electrons (oxidized)- Oxygen gains electrons (reduced)Example 2: Zinc with copper sulfateZn + CuSO₄ → ZnSO₄ + Cu- Zinc loses electrons: Zn → Zn²⁺ + 2e⁻ (oxidation)- Copper gains electrons: Cu²⁺ + 2e⁻ → Cu (reduction)Redox reactions are fundamental in batteries, combustion, metabolism, and corrosion processes.

A redox reaction is a chemical reaction that involves both reduction and oxidation. In oxidation, a substance loses electrons, while in reduction, a substance gains electrons. Example: Zn + CuSO₄ → ZnSO₄ + Cu - Zn is oxidized (loses electrons) - Cu²⁺ is reduced (gains electrons)

Hey chemistry buffs! As a science teacher, I can break down redox reactions. A redox reaction (reduction-oxidation) is a chemical reaction where oxidation (loss of electrons) and reduction (gain of electrons) happen simultaneously. One substance loses electrons (oxidized), while another gains them (reduced).Example: Burning of magnesium: 2Mg + O₂ → 2MgO Here, magnesium (Mg) loses 2 electrons to form Mg²⁺ (oxidation), and oxygen (O₂) gains electrons to form O²⁻ (reduction). You can see this when magnesium burns with a bright flame, forming white magnesium oxide.I did this experiment in class, and the kids loved the spark! Redox is key in batteries, corrosion, and even metabolism. Check ChemLibreTexts for more examples. What’s your favorite redox reaction?

Hi! I’m a chem major, and redox reactions are super cool because they power so much, like batteries! They involve oxidation (when a substance loses electrons) and reduction (when another gains electrons) happening together. Example: Rusting of iron: 4Fe + 3O₂ → 2Fe₂O₃ Iron (Fe) loses electrons to form Fe³⁺ (oxidation), while oxygen gains electrons to form O²⁻ (reduction). I saw rust on my old bike and realized it’s a redox reaction in action! These reactions are everywhere, from fuel cells to photosynthesis. BBC Bitesize has a great overview. Anyone else geek out over chemistry?
