Ammonium Sulfide Formula
[Click Here for Sample Questions]
The chemical compound ammonium sulfide is formed of sulfur and ammonium ions. Because of its explosive properties, it is also known as a "stink bomb." The IUPAC name of this compound is ammonium sulfide, and the molecular formula of ammonium sulfide is (NH4)2S. The ammonium sulfide chemical formula 68.154 g/mol can be used to calculate the molar mass of ammonium sulfide.
Due to the presence of two ammonium ions in the ammonium sulfide formula, it is also known as Diammonium sulfide. For the photograph and textile industries, this chemical is essential as it is commonly used to develop pictures and manufacture textiles.
Ammonium hydroxide is treated with an excess of hydrogen sulfide to produce ammonium hydrosulfide ((NH4)HS), which is then treated with the equivalent amount of ammonia to produce ammonium sulfide.

Ammonium Sulfide is a yellow-orange colored compound. It is crystalline solid at temperatures below -18 C. Furthermore, when it comes to the smell, it has an unpleasant odor that is similar to that of rotten eggs and ammonia.
Additionally, Ammonium Sulfide has a melting point of 0°C and a boiling point of 40°C. Also, Ammonium Sulfide has a density of 1 g mL-1. Water and ethanol are the only two things that can dissolve it. On the other hand, Toluene, benzene, hexane, and ether are not soluble in it. Most critically, it becomes unstable at temperatures over 0° C.

Ammonium Sulfide is used in various things. Ammonium sulfide is most commonly used in the manufacture of photographic developers. In the textile industry, it is also often used. This chemical is used as a patina that may be applied to bronze which means a thin layer typically of green color that is formed on the bronze surface due to oxidation. Not only that but Ammonium Sulfide can also be used as a reducing agent in some chemical synthesis procedures.

With ammonium sulfide, one must be cautious. It is so since it has the ability to irritate the eyes, mucous, and skin. Furthermore, the compound's foul odor may make one feel uneasy. Above all, keep it away from the fire because it is flammable and can cause significant damage if exposed to it.
Things to Remember
- The ammonium sulfide solution is usually formed of an ammonium sulfide solution in water sealed inside a glass ampoule. As the ampoule is broken, giving the solution a powerful and unpleasant odor.
- Ammonium sulfide has the chemical formula (NH4)2S and is highly flammable.
- The melting point of ammonium sulfide is 0°C, and the boiling point is 40°C—also, a density of 1 g mL-1.
- It is not soluble in Toluene, benzene, hexane, or ether, and it is unstable at temperatures above 0 °C.
Sample Questions
Ques: What is (NH4)2S? known as? (2 marks)
Ans: Sulfur and ammonium ions are the two main constituents. Around the sulfur atom, there are two ammonium ions. Two ammonium ions are positively charged in the molecule, while the sulfur atom has a charge value of two and is negatively charged. As a result, the neutralized compound has a sulfur anion with a -2 charge, which is a sulfide characteristic. Hence, ammonium sulfide is the name assigned to the provided chemical. Due to the presence of two ammonium groups in the chemical, it is also known as diammonium sulfide.
Ques: What is Ammonium Sulfide Formula ? To prepare ammonium sulfide, what reaction is required? (2 marks)
Ans: Ammonium sulfide is an inorganic compound because of the presence of sulfur. It is a dangerous and explosive chemical with a powerful and unpleasant odor. It is composed of two ammonium ions centered around a sulfur atom. Ammonium sulfide is made by reacting ammonia with hydrogen sulfide.
Ques: What are the uses of Ammonium Sulfide? Is it soluble in water? (3 marks)
Ans: Ammonium sulfide is often known as a " stink bomb because of its strong odor caused by its ingredient sulfur; ammonium sulfide is often known as a "stink bomb." It's primarily used in the developing photographic industry, textile sector, and bronze patina. They make use of the reducing property of ammonium sulfide. It is also employed in specific chemical synthesis procedures. Water and ethanol are the only two things that can dissolve Ammonium sulfide. Whereas on the other hand, it is insoluble in Toluene, benzene, hexane, and ether.
Ques: Why does Ammonium Sulfide smell so bad and what are its health effects? (2 marks)
Ans: Ammonium sulfide is a volatile compound that breaks down into ammonia and hydrogen sulfide. The dissolved ammonium sulfide rapidly decomposes and releases large volumes of the odorous gas as soon as the container is shattered. It's incredibly stinky, but it's also extremely deadly. Ammonium Sulfide can irritate the eyes, mucous, and cause skin irritation. The compound's terrible odor may also make one feel uncomfortable.
Ques: What are the Melting and Boiling points of Ammonium Sulfide? Mention key elements in ammonium sulfide. (2 marks)
Ans: The melting point of ammonium sulfide is 0°C, and the boiling point is 40°C. In addition, the density of ammonium sulfide is 1 g mL-1. The chemical formula for ammonium sulfide is (NH4)2S, and its molar mass is 66.122 g mol-1. Two ammonium cations NH4+ are connected to one centered sulfur atom to form the molecule.
Ques: Is ammonium sulfide the correct name of this? (2 marks)
Ans: The "stink bomb," which is the other term for ammonium sulphide, is a hazardous substance with an extremely strong and unpleasant odour. They are extremely flammable, and the chemical formula for ammonium sulfide is (NH4)2S. Ammonium hydroxide is treated with an excess of hydrogen sulfide to produce ammonium hydrosulfide ((NH4)HS), which is then treated with the equivalent amount of ammonia to produce ammonium sulfide.
Ques: How is ammonium sulfide prepared? (3 marks)
Ans: By passing hydrogen sulfide gas through a concentrated ammonia solution, ammonium hydrosulfide solutions can be made. At normal temperature, hydrogen sulfide combines with concentrated aqueous ammonia solution to form (NH4)2S. 2(NH4)HS, according to a comprehensive 1895 report. (NH4)2S. 2(NH4)HS is obtained by cooling this species to 0 °C and treating it with additional hydrogen sulfide. The hydrosulfide is produced by passing hydrogen sulfide through an ice-cold solution of this material held at 0 °C.
An aqueous solution of ammonium sulphide is the most frequent "stink bomb." Ammonia and hydrogen sulfide gasses are easily formed from the mixture. This conversion demonstrates how simple the following equilibrium is to achieve: NH3 + H2S = (NH4)SH. The odors of ammonia and hydrogen sulfide are both strong and unpleasant.
