SUMMARY
KMnO4 (Potassium permanganate) oxidizes iodide ions (I-) to iodine (I2) in acidic medium due to its strong oxidizing properties, while in alkaline medium, it oxidizes I- to iodate ions (IO3-). The reaction dynamics differ based on pH levels, with acidic conditions favoring the formation of I2. In contrast, the presence of alkaline conditions facilitates the oxidation of I- to IO3-. This behavior is supported by the information provided in iodometric titration resources.
