Ammonium chloride in bags

Colorless crystal or white granular powder, is a strong electrolyte, soluble in water ionization of the ammonium ions and chloride ions, ammonia and hydrogen chloride production of ammonium chloride will have white smoke. nothing

ammonium chloride

Odor. Taste salty cold and slightly bitter. Moisture absorption is small, but also can absorb moisture in wet and rainy weather. Powdery ammonium chloride is extremely easy to deliquescence, qualified products especially, hygroscopic point general at 76%, when the air relative humidity is greater than that of moisture absorption, ammonium chloride is produced absorption of moisture, easy to agglomerate. Can be sublimation (in fact, the decomposition of ammonium chloride and the process of re generation) without melting point. Relative density 1.5274. The refractive index of 1.642. Low toxicity, half lethal dose (rat, oral) 1650mg/kg. Irritating. Heated to 350 degrees Celsius, boiling point 520.

Soluble in water, slightly soluble in ethanol, soluble in liquid ammonia, insoluble in acetone and ether. Hydrochloric acid and sodium chloride can reduce its solubility in water and its solubility in water to 0 DEG C for 29.4g, 10 DEG C for 33.2g, 20 DEG C for 37.2g, 30 DEG C for 41.4g and 40 DEG C for 45.8g and 50 DEG C for 50.4g and 60 DEG C for 55.3g and 70 DEG C for 60.2g, at a temperature of 80 DEG C for 65.6g and 90 DEG C for 71.2g and 100 DEG C for 77.3g). Heated to 100 DEG C when begin to decompose and 33.78 DEG C can be completely decomposed to ammonia and hydrogen chloride gas, cold again combine to form tiny particles of ammonium chloride and appear as white smoke, not easy to sink, but also extremely easy to and then dissolved in water.

Aqueous solution of pH: because of the hydrolysis of ammonium ions in the water to make the solution significantly acidic, saturated ammonium chloride solution at room temperature pH value is generally around 5.6. 25 at 1%, 5.5, 3%, 10%, 5, 5.1. The ammonium chloride itself can be used as a stable reagent for bismuth and antimony, and the compound is dissolved in dilute hydrochloric acid with ammonium chloride when the chloride ion is coordinated.
