Strontium iodide (SrI2) 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 [1].

Reactions

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[2].
