Calcium iodide Specification
Calcium iodide ,its cas register number is 10031-31-9.It is the inorganic compound; and also can be called Crystal calcium iodide .Its properties are similar to those for related salts, such as calcium chloride.
Calcium iodide (CAS NO.10031-31-9) slowly reacts with carbon dioxide and oxygen in the air, liberating iodine, which is responsible for the faint yellow color of impure samples.Henri Moissan first isolated pure calcium metal by reducing calcium iodide with pure sodium metal.
