💜🧪 FROM PURPLE TO BROWN — ETHANOL OXIDATION IN ACTION! 🤎✨ Every drop tells a chemical story! 👀 Purple potassium permanganate meets ethanol, the colour changes, and a brown precipitate gradually appears. But what’s happening behind the scenes? 🔬 ⚗️ The chemistry explained: 💜 Potassium permanganate (KMnO₄): Acts as an oxidising agent. 🧪 Ethanol (C₂H₅OH): Undergoes oxidation. 🤎 Manganese dioxide (MnO₂): The brown precipitate that can form as permanganate is reduced, depending on the reaction conditions. 🧠 The takeaway: Colour changes can reveal the oxidation and reduction processes occurring in a chemical reaction! 💬 What caught your attention most — the purple colour disappearing or the brown precipitate forming? 👇 ⚠️ This demonstration requires appropriate laboratory supervision and chemical safety precautions. #Chemistry #Ethanol #KMnO4 #RedoxReaction #Oxidation
