Ammonium nitrate is white, similar to ammonium sulfate, easy to get wet, easy to absorb water and cause agglomeration, easily decomposed by heat, ammonium chloride is white or yellowish, white crystal, soluble in water, strong in water absorption, easy to agglomerate, in the process of melting It can be seen that the unmelted portion is yellow. Ammonium bicarbonate is white or slightly gray, with strong odor, direct decomposition by heating, and no signs of melting.
