Ammonium iodide, with the chemical formula NH4I, is a salt of hydroiodic acid. It is a white, crystalline solid that is highly soluble in water. Ammonium iodide is a hygroscopic compound, meaning it readily absorbs moisture from the air. This property necessitates careful storage and handling to prevent deliquescence (dissolving in its own water of hydration).
