Calcium iodide
Introduction
Overview
Overview
Calcium iodide (CaI2) is an ionic compound of calcium and iodine. It is highly soluble in water and it is deliquescent. It is a salt that is solid at room temperature, and it behaves as a typical ionic halide. Because of its hygroscopic nature, it must be kept in tightly-sealed containers. It is similar to calcium chloride in many respects[1]. It is used in photography[2].
Reactions
Reactions
Henri Moissan first isolated pure calcium metal by reducing calcium iodide with pure sodium metal[3]:
Calcium iodide can be formed by reacting calcium carbonate with hydroiodic acid[4]:
Calcium iodide slowly reacts with oxygen and carbon dioxide in the air, giving free iodine[5].
