Inorganic Iodides - Potassium Iodide Photo Brochure

Deepwater Chemicals, Inc. PIS101.84.1.03 Revised 08/04/2006 PRODUCT INFORMATION SHEET POTASSIUM IODIDE PHOTO GRADE FORMULA: KI DESCRIPTION: Colorless or white crystals or granular powder; slightly hygroscopic in moist air. Tends to cake during storage. On long exposure to air becomes yellow due to liberation of iodine. Light and moisture accelerates decomposition.
