This introduces a simple and feasible method of identification of ammonium nitrate
( 1 ) Look fertilizer shape. Crystalline and granular ammonium nitrate were two different forms.
( 2 ) to see colors. Ammonium nitrate
is the appearance of white or light yellow , no visible mechanical magazine .
( 3 ) smelling odor. Ammonium nitrate preservation is good, there should be no odor.
( 4 ) observation of deliquescence situation . A small amount of ammonium nitrate in a clean bowl , the observed deliquescence situation . If the weather is wet, manure quickly into water ; under humidity not the case, it may put more than two hours into the water .
( 5 ) observed dissolution . Use colorless or white glass bowl , add a small amount of ammonium nitrate to the inside , to which was added water, use a clean spoon stirring or shaking , ammonium nitrate can be found quickly dissolved in water.
( 6 ) pH test strip into the observed pH ( 4 ) was found strip turns red, the solution was acidic .
( 7 ) see iron burning reactions. After the red-hot iron , on top of a small amount of ammonium nitrate , ammonium nitrate can be found side burner , while White smoke and emit irritating ammonia odor , no residue on the iron melted .
Ammonium nitrate is normally provided by a large -scale production , product quality is reliable. If a farmer friend buy administered ammonium nitrate, fertilizer is not found satisfactory, the sample can be sent to the fertilizer quality supervision and inspection departments for examination and judgment to determine eligibility to purchase ammonium nitrate .
