Ammonium sulfide, also known as the “stink bomb,” is a toxic chemical and has a very strong and unpleasant odour. They are highly flammable and the ammonium sulfide molecular formula is represented as follows (NH4) 2 S. Ammonium sulfide is an inorganic salt with a sulfurous odor, which is commonly used in the food industry as a flavoring agent. The influence of ammonium sulfide treatment on (100)GaAs (gallium arsenide) surfaces has been studied by X-ray photoelectron spectroscopy (XPS) and reflection high-energy electron diffraction (RHEED). Ammonium Sulfide is a yellow, crystalline (sand-like) solid that is usually in a water solution. It has a very strong rotten egg and Ammonia odor and is used in “stink bombs,” photographic developing and textile manufacturing.
