Iodine solution , 0.5 mol I2/l - 1 N volumetric solution, 1 l, glass

Iodine solution is a ready-to-use volumetric reagent prepared at 0,5 mol I2/l, corresponding to a 1 N volumetric solution for quantitative laboratory titration work. The solution is filled in a 1 l glass pack and shows a density of 1,288 g/cm³ with a boiling point of approximately 100 °C, data that support handling, dosing and temperature considerations during analytical use. As a defined iodine volumetric medium, it is intended for procedures that specify iodine titre at this concentration, reducing the need for in-house standardisation from solid iodine when a factory-prepared solution is preferred. Material from manufacturer Carl ROTH is presented for chemical laboratory inventories that require consistent volumetric iodine for iodometric and related titrations. The 1 l glass presentation suits regular bench consumption while protecting the solution during storage and dispensing. Density information aids volume-to-mass conversions where gravimetric checks are applied, and the near-100 °C boiling point reflects the aqueous character of the preparation. This volumetric iodine solution supports routine analytical chemistry, teaching laboratories and quality-control settings that call for 0,5 mol I2/l (1 N) iodine without additional on-site concentration adjustment.
