Why can’t iodide be oxidised to iodate in acidic medium?

Even if we use a strong oxidising agent like ‘permanganate ion in acidic medium’ it doesn’t help oxidise iodide to iodate, but a relatively weaker oxidising agent ‘permanganate ion in alkaline medium’ helps to form iodate from iodide. I have found one discussion similar to this but it’s not convincing. Even in alkaline medium the […]
