And ammonia, and ammonia are widely used in various fields of human activity. We often hear that ammonia is a solution of ammonia in water. But not everything is so simple, it will tell you any chemist. So, about the difference of ammonia from the ammonia, and will be discussed below.

A bit of history
Ammonia was first obtained by English chemist Joseph Priestley (by the way, both the priest – a strange combination, isn’t it?) in 1774. He called the gas «alkaline air», chemical composition of which couldn’t define. Did it 11 years later, in 1785, the French chemist Claude Louis Bertholle, also known as the inventor of «potassium chlorate salt» – part, widely used in medicine and pyrotechnics. Why gas got this name?
There are two versions, one of which is associated with the name of the ancient Egyptian God Amun, and the second – with a similar sounding oasis of Ammon in North Africa. The first is that worship Amon the people during the ceremony smelled ammonia (chemical formula NH4Cl), when heated releasing ammonia. According to the second version, in the oasis of Ammon, on the crossroad of brisk caravan routes, as a result of the permanent presence there of a large number of pack animals congregated in huge number of products of their vital activity. And urea, decomposing rapidly in the hot climate, excretes ammonia. Which of the two versions is correct is unknown.
The difference of ammonia from ammonia primarily in the fact that in normal conditions they are in different aggregate States. Ammonia – gas, the conductor that easily liquefied at a temperature of about -33 Celsius. And ammonia – liquid that has the same unpleasant odor, and ammonia. Interesting fact: for transportation of ammonia from Togliatti to Odessa laid the unique ammonia pipeline with a length of about 2,1 thousand kilometers.
to content ↑Application
Ammonia is one of the most important products of the chemical industry. It has found application in the following industries:
- as a refrigerant in refrigerating equipment (mostly in industrial settings);
- the production of ammonia;
- manufacture of explosives;
- the production of fertilizers;
- the construction (consisting of antifreeze additives in solutions);
- the production of polymers, nitric acid, soda;
- some other industry.
The use of ammonia more narrowly. The lion’s share is used in medicine mainly as an antiseptic, or a means for output from fainting. He found the application and in everyday life. Housewives know that ammonia is perfectly displays clothes with stains of different origin.

It is considered that ammonia is a solution of ammonia in water, but… But in fact the process of turning ammonia into ammonia has not one notch but two. The first step is the formation of ammonia hydrate of ammonium. And the second is the dissolution of the obtained hydrate in water to form the composition, which is called «ammonia».
The first stage is expressed by the following formula: NH3 + H2O ⇄ NH3 · H20 ⇄ NH4+ + OH- . And only later directly to the formation of ammonia. Although, in essence, such a division is simply a quibble. Master in refrigeration plants where ammonia is used, not chemical formulas themselves, I’m just putting the hose, where does the ammonia in a bucket of water, and get the right amount of ammonia, which is then used for their own needs (mainly in life). The saturation limit of the solution is determined at the hearing: when you start the characteristic clicks and POPs all the gas can be shut off, ammonia is ready!

And in conclusion, to summarize, what is the difference between ammonia and ammonia.
The gas liquefies at -33 degrees Celsius, which is used in industrial refrigeration applications
Actually – aqueous solution of ammonia
The scope of
The production of a wide range of products – explosives, fertilizers, caustic soda, nitric acid, polymers and more. Also used for the production of ammonia as a refrigerant in industrial refrigeration systems
In medicine – as an antiseptic and remedy for removing from the unconscious state, in the home – as an effective stain remover
