The method is a USP method and titrates sodium iodide with 0.05M potassium iodate VS using amaranth TS as an idicator. So I should use KMnO4? How should I go about setting up the standardization?
So you need to standardize iodate solution, not iodide, right? Potassium iodate is a standard substance, to prepare standardized solution you just need to weight KIO3
used for solution preparation.
