Ammonium Iodide is a chemical compound with a formula NH4I and can be manufactured in a lab by treating ammonium hydroxide with hydrogen iodide gas. It is easily soluble in water and ethanol. In moist air, it decomposes and turns yellow with the liberation of iodine. In this article, let us learn more about the ammonium iodide formula, its chemical structure along with its properties and uses.

Ammonium Iodide Chemical Structure
Ammonium Iodide Uses
- Used in photographic chemicals
- Used in medicines
Preparation
Firstly we dissolve 254 grams of the potassium iodide in 125 ml of water (H2O) and mix it with 100 grams of ammonium sulfate. Then we have to dissolve in 125 ml of boiling water. After it cools down, we add 40 ml of alcohol and then we keep the mixture for a time period of 12 hours.
However, then we obtain a precipitate of potassium sulfate that we filter and then we evaporate the filtrate occasionally by adding ammonia water that is containing some amount of alcohol until the process of crystallization starts. Then the crystals of the potassium sulfate are additionally washed with the dilute alcohol that is about 20 percent. Moreover, after combining the filtrates and evaporating finally the ammonium iodide is obtained as a result.
(NH4)2SO4+ 2KI →2NH4I + K2SO4
The ammonium iodide crystallizes in the shape of cubes and deliquesces in the air. We have to preserve it in a dark place because the light decomposes the salt, causing it to turn brown in color. We can remove this coloration by dissolving it in distilled water.
After that, then treating the solution with the ammonium sulfide, filtering, and evaporating the filtrate with the help of the steam bath, to crystallize. It is readily soluble in alcohol. The aqueous solution turns yellow in color on standing, owing to the decomposition and separation of the iodine. One part of the salt dissolves in 0.60 parts of the water (H2O).
The ammonium iodide can also be made in a laboratory. By the process of reacting ammonia or ammonium hydroxide with the hydroiodic acid or the hydrogen iodide gas:
NH3+ HI → NH4I
NH4OH + HI → NH4I + H2O
Uses
The ammonium iodide is useful in many ways and one of them is in photographic chemicals. Moreover, we also generally use it in the process of making various types of medicines.
Safety and Health Hazards
Due to the inhalation of the ammonium iodide a person may suffer from multiple health issues, some of them are irritation of nose and throat. Contact of the ammonium iodide with the naked eyes of a living being can cause irritation in the eyes. The toxic and irritating fumes of the hydrogen iodide, iodine, and oxides of nitrogen may result in the fire. The compound may sublime into the fire and then condense on the cold surfaces. The ammonium iodide should be kept in a tightly closed and protected container and the sunlight should not enter that container.
Ammonium Iodide Overview
Ammonium Iodide is an inorganic compound with the formula NH4(+) and is the major component of a compound of the same name, a yellowish-orange solid that is also used as a fertilizer. Ammonium Iodide is a radioisotope that is used as a radioisotope tracer for the study of water flow through soils, rocks, and other porous media.
Ammonium Iodide is a very interesting compound that has been around for several years. It’s been used in a wide variety of applications, such as glass production, construction, concrete, and more.
Iodate, one of the most important additives in the field of explosives, is an important building block in the production of explosives. Many of the industrial grade explosives produced are heavy metals, resulting in the requirement of increasing the reaction speed in order to meet the growing demands for these explosives. Ammonium iodate is an important intermediate in the industrial synthesis of explosives.
Ammonium Iodide, also known as Aqua-Iodine, is a chemical compound with the formula NH4I. It has been used as an antifouling agent in marine environments, and is also a component of textile dye. It is a white crystalline compound, which is hygroscopic and has a pungent odor. It is a weak base, and is soluble in water.
The boiling point of Ammonium Iodide usually gets overlooked. It’s a bit tough to read, but the boiling point is 185.4 degrees C, which is higher than the boiling point of Ammonium Iodide itself (180.9 C). Ammonium Iodide is commonly used in the manufacture of fire extinguishers, explosives, and color dyes.
Ammonium Iodide (NH4IO3), also known as “Ammonium Permanganate”, is a compound that is used for water treatment and for mining of the ores of rare earth elements. It is mainly used as a water disinfection agent. The melting point is around 154-155 degrees Celsius.
Ammonium Iodide (AI) is a synthetic chemical element that was first discovered in the form of perchlorate in 1785. In 1863, the element was found to be insoluble in water, so it was only used as a component in many types of explosives. It was used as a fertilizer in the late 1800’s.
As a new technology, a few people wonder if the chemical will ever be safe, and if so, what safety precautions should be taken. For those who are curious about a certain chemical, citychem.com has the answer. Our site is a database of chemicals. Our goal is to provide the public with the knowledge they need to know about a chemical at the point of exposure.
Ammonium Iodide is commonly found in household products like deodorants, etc. and is a fertilizer that is commonly used to boost the growth of crops. It is also used to control the growth of algae in swimming pools and to disinfect swimming pools. Ammonium Iodide is also used to treat certain kinds of water after a disaster.
Solved Example on Ammonium Iodide Formula
Question: How to prepare methyl ammonium iodide for lead iodide perovskite?
Solution: Addition of CH3NH2 and HI at ice-cold conditions then stir for 2 h, followed by heating at 80-90oC for 3 h, eventually, you will get while solid. This one should go for washing with ether multiple times and dried in an oven at 600C for one day.
In detail, you can find in nature paper about the preparation of CH3NH3I.
Is Ammonium iodide dangerous?
Ammonium iodide causes several health issues to a person who inhales, majorly it causes irritation of the nose and throat. High exposure to Ammonium iodide without precautions causes Eye and skin irritation. The toxic and irritating fumes from the iodine results in the fire explosion. The Ammonium iodide can be stored in a well-closed container with a tight lid and kept away from sunlight.
How do you make Ammonium iodide?
Answer:
- Ammonium iodide is prepared by reacting Ammonia or Ammonium hydroxide with Hydroiodic acid or Hydrogen iodide.
