NH₄I is an acidic salt.
When an aqueous solution contains such salt, then the pH of the aqueous solution is less than 7. The pH of the aqueous solution depends upon the salt ions, and how strong an ion acts with water molecules. The aqueous solution of a salt produced by a strong acid and a weak base is acidic in nature.
NH4I is the chemical name for ammonium iodide. It is a component of various medicines and photography chemicals. Hydroiodic acid may be used to make it by reacting with ammonia. It is readily soluble in water, where it forms cube-shaped crystals. It dissolves in ethanol as well. When exposed to damp air, it progressively becomes yellow as a result of iodine being released during decomposition.
