Identification of nitrogen fertilizers
Nitrogen Fertilizer: The single chemical fertilizer color should be the same, and it can be completely dissolved in the water. If the fertilizer is put on the red iron flakes, ammonia will be released. In the experiment of burning iron tablets, ammonium sulfate emits a purple flame, buzzing, and there is residue; when urea is burned, if a glass sheet is touched with white smoke, a white crystalline material can be seen on the glass sheet; Crystallized, and after the smoke out of the Mars is ammonium nitrate; in the burning of red iron only melt no smoke, the odor is the ammonium bicarbonate; after the touch of iron tablets smell like hydrochloric acid is ammonium chloride.
