The Basics of NH3 Lewis Acid and Base
In chemistry, NH3 is known as ammonia, which is a colorless gas that has a pungent smell. It is a Lewis base because it donates its lone pair of electrons to form a coordinate bond with a Lewis acid. NH3 is a weak base because it does not dissociate completely in water. It reacts with acids to form salts and with metals to form complex ions.
The Lewis Acid and Base Theory
The Lewis acid and base theory is a concept that was introduced by Gilbert N. Lewis in 1923. The theory states that a Lewis acid is an electron pair acceptor, while a Lewis base is an electron pair donor. The acid-base reaction involves the formation of a coordinate covalent bond between the acid and the base.
The Properties of NH3 as a Lewis Base
NH3 is a Lewis base because it has a lone pair of electrons that it can donate to form a coordinate bond with a Lewis acid. The strength of NH3 as a base depends on the electronegativity of the elements to which it is bonded. The greater the electronegativity, the weaker the base. NH3 is a weak base because it does not dissociate completely in water.
The Properties of NH3 as a Lewis Acid
NH3 can also act as a Lewis acid by accepting a lone pair of electrons from a Lewis base. The strength of NH3 as an acid depends on the availability of its lone pair of electrons. The greater the availability, the stronger the acid. NH3 can form coordinate covalent bonds with Lewis bases such as H2O, F-, and NH3 itself.
Applications of NH3 as a Lewis Acid and Base
NH3 is used in various industrial and laboratory applications as both a Lewis acid and base. As a base, it is used in the production of fertilizers, cleaning agents, and in the manufacturing of pharmaceuticals. As an acid, it is used in the production of nylon, dyes, and plastics. NH3 is also used in the preparation of metal complexes and in analytical chemistry.
