The chemical reaction between I- and KMnO4 is known as oxidation, where I- (iodide ion) is oxidized to I2 (iodine) and KMnO4 (potassium permanganate) is reduced to Mn2+ (manganese ion).
The products of the oxidation of I- by KMnO4 are I2 (iodine) and Mn2+ (manganese ion).
KMnO4 is used as an oxidizing agent in the reaction because it has a high standard reduction potential, meaning it is a strong oxidizing agent that can easily oxidize other substances.
The rate of the oxidation reaction can be affected by factors such as temperature, concentration of reactants, and the presence of catalysts. Higher temperatures and concentrations generally increase the rate of the reaction, while the presence of a catalyst can speed up the reaction by lowering the activation energy.
The oxidation of I- by KMnO4 is commonly used as a titration method in analytical chemistry to determine the concentration of reducing agents. It is also used in organic synthesis to oxidize alcohols to aldehydes or ketones, and in water treatment to remove impurities and disinfect water.
