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 here 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 .
