Ammonia of 25%

Ammonia — NH3, hydrogen nitride, under normal conditions — colorless gas with pungent characteristic smell (smell of spirit of ammonia), is almost twice lighter than air. Ammonia easily passes into colorless liquid with density of 681,4 kg/m ³, strongly refracting light. Like water, liquid ammonia is strongly associated, mainly due to formation of hydrogen bonds. Liquid ammonia practically does not carry out electric current. Liquid ammonia — good solvent for very large number organic, and also for many inorganic compounds. Solid ammonia — colourless cubic crystals.

Ammonia is among the most important products of chemical industry, its annual world production reaches 150 million tons. It is generally used for production of nitrogenous fertilizers (nitrate and ammonium sulfate, urea), explosive substances and polymers, nitric acid, soda (by ammoniac method) and other products of chemical industry. Liquid ammonia is used as solvent.

In refrigerating equipment it is used as the refrigerating agent (R717)

In medicine of 10% the ammonia solution more often called by spirit of ammonia is applied at unconscious states (to initiation of breath), to stimulation of vomiting, and also outwardly — neuralgia, miozita, stings of insects, to processing of hands of the surgeon. At misapplication can cause burns of gullet and stomach (in case of reception of not divorced solution), reflex respiratory standstill (at inhalation in high concentration).

Apply locally, it is inhalation and inside. For initiation of breath and removal of the patient from unconscious state carefully bring the small piece of gauze or cotton wool moistened with spirit of ammonia to the patient's nose (on 0,5 - 1 c). Inside (only in cultivation) for induction of vomiting. At stings of insects — in the form of lotions; at neuralgia and miozita — grindings by ammoniac liniment. In surgical practice part in warm boiled water and wash hands.

As ammonia is mild base, at interaction with acids it neutralizes them.

Physiological effect of spirit of ammonia is caused by pungent smell of ammonia which irritates specific receptors of mucous membrane of nose and promotes excitement of the respiratory and sosudodvigatelny centers of brain, causing increase of breath and increase of arterial pressure.

The antifrosty additive for dry construction solutions relating to accelerators. The recommended dosage — 2 … 8% of mass of components of dry blend depending on application temperature. Ammonium hydroxide — product (NH3 * H2O) representing the gaseous NH3 ammonia dissolved in water.
