WebWhat is Iodometric titration. Iodometric titration, also known as Iodometry, is a type of indirect titration. The analyte solution is an oxidizing agent in Iodometric titrations. It is reacted with an excess amount of potassium iodide (KI). The oxidizing agent oxidizes iodide (I–) ions into iodine (I2). WebFor example, the reaction: H 3 AsO 3 + I 2 + H 2 O → H 3 AsO 4 + 2 H+ + 2 I-. is reversible at pH < 4.
