Theory:
Oxidation of ethanol can be carried out by using an oxidizing agent like alkaline potassium permanganate (KMnO₄) or acidified potassium dichromate (K₂Cr₂O₇). The oxidizing agent removes hydrogen from ethanol and adds oxygen to it, resulting in the formation of acetic acid (CH₃COOH).
The chemical reaction is:
CH₃CH₂OH + [O] → CH₃COOH + H₂O
Here, [O] represents an oxygen atom supplied by the oxidizing agent.
Oxidation of Ethanol Experiment – Class 12 Science
Oxidation of Ethanol is a fundamental Class 12 science experiment in organic chemistry. This experiment showcases how a primary alcohol like ethanol reacts with an oxidizing agent to form acetic acid—a transformation that introduces students to key chemical reactions and oxidation processes in organic compounds.
In the oxidation process, ethanol (CH₃CH₂OH) is exposed to a strong oxidizing agent such as acidified potassium dichromate (K₂Cr₂O₇) or alkaline potassium permanganate (KMnO₄). These agents help in removing hydrogen atoms from ethanol and supplying oxygen atoms, resulting in the formation of acetic acid (CH₃COOH) and water.
Chemical Reaction:
CH₃CH₂OH + [O] → CH₃COOH + H₂O
This experiment is crucial for understanding the broader concept of oxidation in organic chemistry and its real-life applications, such as in the production of vinegar or metabolism of alcohol in the human body.
