Ammonium iodide

Chemical properties

white to light yellow crystalline powder

The Uses of Ammonium iodide

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.

The Uses of Ammonium iodide

It is used in photographic chemicals and some medications. It is a catalyst for dethioacetalization reaction.

The Uses of Ammonium iodide

In photographic chemicals.

What are the applications of Application

Ammonium iodide is an iodide salt used as a reagent and expectorant

Definition

ChEBI: The iodide salt of ammonia.

General Description

Odorless white solid. Sinks and mixes with water.

Air & Water Reactions

Water soluble.

Reactivity Profile

Ammonium iodide is light sensitive, becomes yellow or brown on exposure to air and light because of liberation of Iodine [Merck 11th ed. 1989]. Bromine trifluoride reacts explosively with the following ammonium bromide, ammonium chloride, Ammonium iodide [Mellor 2 Supp. 1:165 1956].

Health Hazard

Inhalation causes irritation of nose and throat. Contact with eyes causes irritation.

Flammability and Explosibility

Not classified

Purification Methods

The iodide crystallises from EtOH on addition of ethyl iodide, and is very hygroscopic. Store it in the dark. Its solubility is 177g in 100g of H2O at 25o. [Schmeisser in Handbook of Preparative Inorganic Chem (Ed. Brauer) Academic Press Vol I p 289-290 1963.]
