DescriptionAmmonia, also known as NH3 or amoniaco, belongs to the class of inorganic compounds known as homogeneous other non-metal compounds. These are inorganic non-metallic compounds in which the largest atom belongs to the class of 'other non-metals'. Ammonia is a very strong basic compound (based on its pKa). Ammonia exists in all living species, ranging from bacteria to humans. Ammonia is a potentially toxic compound.
