Redox Titration: Know Definition, Types, Principle, Indicators

WebIodimetry is a redox titration that uses iodine as the titrant. Although iodines oxidizing power is less than that of ceric, permanganate and dichromate ions, it is widely used as redox titrant because of its ability to react rapidly with many strong reductants, and the availability of a good indicator for iodine which is starch.
