Ammonium chloride is a colorless crystal or white crystalline powder; odorless, taste salty, cool; have cited moist. This product is soluble in water, slightly soluble in ethanol.
Colorless cubic crystal or white crystalline powder. Salty and bitter cold, soluble in water was acidic, PH value is generally around 5.6. The relative density of 1.527. Soluble in water, slightly soluble in ethanol, soluble in liquid ammonia, insoluble in acetone and ether. When heated to 100 °C showed distinct volatile, 337.8 °C when the dissociation of ammonia and hydrogen chloride, and then re-freeze small particles combine to form ammonium chloride and white smoke, not easy to sink, is also very difficult to be dissolved in water. Sublimation heated to 350 °C, boiling point 520 °C. Moisture absorption, but in the wet rainy weather can also absorb moisture caking. Powdered ammonium chloride can easily absorb moisture, particularly ammonium wet, moisture is generally about 76%, when the moisture in the air relative humidity is greater than the point, the ammonium chloride which produces the phenomenon of moisture absorption, easy to agglomerate. Slightly acidic aqueous solution when heated acidity. Of ferrous metals and other metals are corrosive, especially for copper corrosion greater, no corrosive effect on the iron.
Mainly used for dry batteries, storage batteries, ammonium salt, leather tanning, electroplating, precision casting, medicine, photography, electrodes, adhesives, yeast nutrients and dough improving agent. Ammonium chloride, referred to as "ammonium chloride", also known as brine sand, is a quick nitrogen chemical fertilizer, nitrogen content is 24% ~ 25%, are physiological acidic fertilizer. It is suitable for wheat, rice, corn, canola and other crops, especially cotton and flax fiber crops have increased toughness and tension and improve the quality of the effect. However, due to the nature of ammonium chloride and if applied wrong way, often give the soil and bring some adverse effects on crops. In addition, there are many farms will be foreign ammonium chloride as a class of non-protein nitrogen to feed cattle and sheep and other animals, but there are stringent restrictions on the amount added. Can be used as fertilizer, is a nitrogen fertilizer, but not with alkaline Ammonia fertilizer with chemical fertilizer application, it is best not to application of saline in order to avoid reducing fertilizer
