Ammonia and ammonium salts can be readily detected, in very minute traces, by the addition of Nessler's solution, which gives a distinct yellow colouration in the presence of the least trace of ammonia or ammonium salts.
The amount of ammonia in ammonium salts can be estimated quantitatively by distillation of the salts with sodium or potassium hydroxide, the ammonia evolved being absorbed in a known volume of standard sulfuric acid and the excess of acid then determined volumetrically.
Sulfur sticks are burnt to detect small leaks in industrial ammonia refrigeration systems. Larger quantities can be detected by warming the salts with a caustic alkali or with quicklime, when the characteristic smell of ammonia will be at once apparent. Ammonia is an irritant and irritation increases with concentration; the
Permissible Exposure Limit is 25 ppm, and lethal above 500 ppm. Higher concentrations are hardly detected by conventional detectors, the type of detector is chosen according to the sensitivity required.
Ammoniacal nitrogen (NH3-N) is a measure commonly used for testing the quantity of ammonium ions, derived naturally from ammonia, and returned to ammonia via organic processes, in water or waste liquids. It is a measure used mainly for quantifying values in waste treatment and water purification systems, as well as a measure of the health of natural and man made water reserves. It is measured in units of mg/L.
1. Physical properties
|Hazardous class for transort||2.3|
2. Typical technical data (COA)
|High Grade||First Class|
|Oil mg/kg ≤||5||1.6|
|Fe mg/kg ≤||1||0.7|
|Cylinder Size||Filling Weight (kg)||
|Fertilizer||Globally, approximately 88% of ammonia is used as fertilizers
either as its salts, solutions or anhydrously. When applied to soil, it helps provide increased yields of crops such as maize and wheat
|Precursor to nitrogenous compounds||Ammonia is directly or indirectly the precursor to most nitrogen-containing compounds|
|Cleaner||Household ammonia is a solution of NH3 in water used as a general purpose cleaner for many surfaces|
|Fermentation||Solutions of ammonia ranging from 16% to 25% are used in the fermentation industry as a source of nitrogen for microorganisms and to adjust pH during fermentation|
|Antimicrobial agent for food products||Anhydrous ammonia is currently used commercially to reduce or eliminate microbial contamination of beef|
Because of ammonia's vaporization properties, it is a useful refrigerant. It was commonly used prior to the popularisation of chlorofluorocarbons (s). Anhydrous ammonia is widely used in industrial refrigeration applications and hockey rinks because of its high energy
efficiency and low cost
|For remediation of gaseous emissions||
Ammonia is used to scrub SO2 from the burning of fossil fuels, and the resulting product is converted to ammonium sulfate for use as fertilizer.
8.As a fuel - The raw energy density of liquid ammonia is 11.5 MJ/L,which is about a third that of diesel
|As a stimulant||Ammonia, as the vapor released by smelling salts, has found significant use as a respiratory stimulant. Ammonia is commonly used in the illegal manufacture of methamphetamine through a Birch reduction|
|Textile||Liquid ammonia is used for treatment of cotton materials, giving properties like mercerisation, using alkalis. In particular, it is used for prewashing of wool|
|Lifting gas||At standard temperature and pressure, ammonia is less dense than atmosphere, and has approximately 60% of the lifting power of hydrogen or helium. Ammonia has sometimes been used to fill weather balloons as a lifting gas|
|Woodworking||Ammonia has been used to darken quartersawn white oak in Arts & Crafts and Mission-style furniture. Ammonia fumes react with the natural tannins in the wood and cause it to change colours|
