Explanation

Correct answer. Bayer's reagent is alkaline Potassium permanganate (KMnO4). An alkaline solution of K2HgI4 is called Nessler's reagent. Chromyl chloride (CrO2Cl2) is known as Etard’s reagent. Fenton's reagent is a solution of hydrogen peroxide and an iron catalyst (FeSO4) that is used to oxidize contaminants or waste water.
