What is the role of MnO4⁻ in acidic medium during redox reactions? (2020)

Step 1: Understand that MnO4⁻ is a chemical species known as permanganate.
Step 2: Recognize that in a redox reaction, there are two main processes: oxidation (loss of electrons) and reduction (gain of electrons).
Step 3: Identify that MnO4⁻ is involved in redox reactions as an oxidizing agent.
Step 4: Know that an oxidizing agent is a substance that gains electrons from another substance during the reaction.
Step 5: In acidic medium, MnO4⁻ accepts electrons and is reduced to Mn²⁺.
Step 6: Conclude that the role of MnO4⁻ in acidic medium is to facilitate the oxidation of other substances by gaining electrons.
