Description and Uses

White crystals made by the action of ammonium hydroxide on hydroiodic acid followed by crystallization. Soluble in water and alcohol, ammonium iodide was used as a halide in collodion formulas, particularly in situations where it was needed for use immediately. Ammonium iodide decomposes quickly when mixed with plain collodion, releasing iodine.
