Ammonia is a colorless gas that is lighter than air. This material is easily recognizable because of its pungent aroma. Ammonia, which can be in the form of gas, liquid, or solid objects, can be contained in various objects and for various uses, such as cleaning products, fertilizers, and supporting materials for the fermentation process.
