Strontium iodide can be prepared by reacting strontium carbonate with hydroiodic acid:
SrCO3 + 2 HI → SrI2 + H2O + CO2 
Strontium iodide yellows when exposed to air. At high temperatures (when in the presence of air) strontium iodide completely decomposes to form strontium oxide and free iodine.


USES

 Strontium iodide is a salt of strontium and iodine. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide.
