Description of clorurodeamonio

• Ammonium chloride is an inorganic compound with the formula NH4Cl and a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic. Sal ammoniac is a name of the natural, mineralogical form of ammonium chloride. The mineral is commonly formed on burning coal dumps from condensation of coal-derived gases. It is also found around some types of volcanic vents. It is mainly used as fertilizer and a flavouring agent in some types of liquorice. It is the product from the reaction of hydrochloric acid and ammonia.

What is Ammonium chloride?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Ammonium chloride   which has developed particularly rapidly in recent years. Do you know about Ammonium chloride?
• The official answer：Ammonium chloride (“ammonium chloride”, also known as halos and, chemical formula: NH4Cl) is a colorless cubic crystal or white crystalline powder. Taste salty, cool, and slightly bitter, acid salt. Relative density 1.527. soluble in water and ethanol, soluble in liquid ammonia, insoluble in acetone and aether. The aqueous solution is weakly acidic, and the acidity increases when heated. It starts to volatilize significantly when heated to 100℃, dissociates into ammonia and hydrogen chloride at 337.8℃, and then recombines to produce ammonium chloride with very small particles and white smoke when cooled, not easy to sink, and not easy to dissolve in the water again. Heating to 350 ℃ sublimation, boiling point 520 ℃. Small hygroscopicity, but in the wet and rainy weather can also absorb moisture caking. Corrosive to ferrous metals and other metals, especially to copper corrosion is greater, with no corrosion effect on pig iron.

What’s the application of Ammonium chloride?

• Ammonium chloride is used as an electrolyte in carbon and zinc dry cells and is used in large quantities in the electroplating industry. Especially in cyanide-free electroplating, ammonium chloride is used more often. For example, in cyanide-free galvanizing, zinc chloride and ammonium chloride are the main components of the electroplating solution, in which zinc chloride and chloride ions form a ligand ion [ZnCl4]2-(or ZnCl3-) with similar properties to [Zn(CN)4]2-, which can continuously dissociate a small amount of Zn2+ ions and deposit them on the cathode plated parts, resulting in a uniform and dense layer. It is used as an important raw material for the synthesis of inorganic polymer compounds. For example, polymeric chain sulfide nitride (SN)x, which is used as superconducting material, is made by the reaction of S2Cl2 and NH4Cl. Highly polymeric chlorophosphorus-nitrophenyl compounds are made by reacting NH4Cl with PCl5, and chloroform-nitrophenyl compounds are obtained by reacting NH4Cl with BCl3. They are called “inorganic benzene” compounds and are a class of non-metallic inorganic materials of great practical value. Others. It can be used as dyeing mordant, analytical reagent, raw material for gunpowder, and also often used as soldering flux, because ammonium chloride and metal oxides produce chloride, which is used to remove the oxides on the metal surface when welding. Ammonium chloride with a content of 99.5% or more can be used as a diuretic, etc.
