WebThis is called an iodometric titration. Most often of all, the reduction of iodine to iodide is the last step in a series of reactions where the initial reactions are used to convert an unknown amount of the solute (the substance being analyzed) to an equivalent amount of iodine, which may then be titrated. WebIt is one of the most ubiquitous vitamins ever discovered. Besides plays a paramount role as an antioxidant and free radical scavenger, it has been suggested to be an effective … Webthe oxidising agents are used to determine the reducing agents, while in reductimetric titrations reducing agents are employed for the determination of oxidising agents. You would also recall from section 10.7.1 of Unit 10 that the I2/2I ‒ couple is of medium oxidising power.
