Iodine 0.2N/0.1M Volumetric Solution according to Wijs 2.5L used in analytical chemistry for oxidation-reduction titrations, where it acts as a standard solution to accurately determine the concentration of reducing agents in a sample by measuring the volume of iodine solution needed to reach an endpoint in a reaction; essentially, it is used to quantify the amount of a substance that can be oxidized by iodine through a chemical reaction.
