The analysis

The claim is a well-established standard chemical fact regarding the redox behavior of potassium permanganate in different pH media. None of the retrieved papers specifically evaluate or test this precise comparative mechanism as their main subject, and it is widely accepted foundational knowledge in chemistry, requiring no citation.
