why is nh3 a weak base

A base is any molecule that accepts a proton, while an acid is any molecule that releases a proton. For this reason, ammonia is considered basic because its nitrogen atom has an electron pair that readily accepts a proton. However, ammonia is classified as a weak base, which is a chemical compound that does not completely dissociate into ions in aqueous solution. When molecules separate into ions, the process is called dissociation. This forms a different chemical structure to be a weak base or a strong acid and vice versa.Elemental ammoniaRead more: why nh3 is a weak base Read more: Why does a small couple divorce Ammonia doesn’t contain any hydroxide ions at first, but when dissolved in water it picks up hydrogen ions from the water to produces hydroxides as well as ammonium ions. However, ammonia does not convert completely to hydroxide and ammonium ions in solution, which is why it is considered a weak base. When it breaks apart, it turns into positively charged ammonium (NH4+) ions and negatively charged hydroxide (OH-) ions, but some of the ammonia molecules remain bound together. Because of the fact that not all molecules break down, dissociation is considered incomplete because only a very small percentage has actually produced hydroxide ions from the ammonia molecules. The classification only makes sense for how the concentration of a given chemical reaction is determined. It does not describe how reactive, oxidizing or caustic they are. Strong bases can be caustic and as dangerous as strong acids. Take anhydrous ammonia for example: it has a pH of around 11.6, but it still causes chemical burns and severe irritation to mucous membranes, skin and eyes, in the same way as exposure to hydrochloric acid (pH). equals 0) to corrode those areas.
