NH₃ - the chemical formula of ammonia.The molecules of the gas are of pyramidal shape, one of whose vertices there is a nitrogen atom.They are formed by hydrogen bonds and exhibit a strong polarity.This explains the unusual physical properties of ammonia: its melting point is about -80 degrees.It is highly soluble in water, alcohols and other organic solvents.

Application ammonia

Ammonia plays an important role in the industry.With it getting nitrogen fertilizers used in agriculture, nitric acid, and even explosives.Ammonia is widely used by doctors, also produced with ammonia.The pungent smell of the gas irritates the mucous membranes of the nose and stimulates the respiratory function.Ammonia is used for fainting or alcohol poisoning.There ammonia or external use in medicine.He is an excellent antiseptic
, which surgeons have treated their hands before surgery.

Ammonia as a product of the decomposition of ammonia, used in soldering metals.At high temperature ammonia from ammonia is obtained that protects against the formation of metal oxide film.

ammonia poisoning

ammonia - a toxic substance.Often occur in the production of this gas poisoning, accompanied by suffocation, delusions and strong excitation.How to help a person who got into this situation?First you need to wash his eyes with water and put on gauze that has been soaked in a weak solution of citric acid.Then you need to bring it out of the zone where there is a high concentration of ammonia.Poisoning is possible at a concentration of about 350 mg / m³.

In case of contact with ammonia on the skin should immediately wash the affected areas with water.Depending on the amount of ammonia gets on your skin, you may experience severe redness or burns with blisters.

the factories, which produces ammonia, introduced strict fire safety measures.The fact that a mixture of ammonia and air is highly flammable.Vessel where it is stored, can easily explode when heated.

chemical properties of ammonia

Ammonia reacts with many acids.This interaction produces a different ammonium salt.Upon reaction with polybasic acids are obtained two types of salts (depending on the number of moles of ammonia).
