    Description

    Iodine is available as bluish-black crystals with a metallic luster and a pungent odor. It is slightly soluble in water (0.03 g/100 g). It is stable under ordinary conditions of use and storage. Iodine is incompatible with ammonia, powdered metals, alkali metals, or strong reducing agents. It reacts violently or explosively with acetaldehyde and acetylene, and reacts with ammonium hydroxide to form shock-sensitive iodides on drying. Iodine is a naturally occurring element that is essential for
