[citation needed], KI is used with silver nitrate to make silver iodide (AgI), an important chemical in film photography. As with other alkali metals, potassium decomposes in water with the evolution of hydrogen because of its reacts violently with water, it only occurs in nature in ionic salts. The name Iodine is derived from the Greek word "iodes" meaning violet. [45], In the Netherlands, the central storage of iodine-pills is located in Zoetermeer, near The Hague. Shipping documentation includes a Certificate of Analysis and Safety Data Sheet (SDS). It absorbs water less readily than sodium iodide, making it easier to work with. (doesn't have to be 1%; 0.5% is fine) Iodine Solution Dissolve 5.00 g potassium iodide (KI) and 0.268 g potassium iodate (KIO 3) in 200 ml of distilled water. : UN1479 Class: 5.1 Pkg. Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine.
