Ammonium Chloride Powder is a white crystalline salt with the chemical formula NH₄Cl, widely used in industrial, laboratory, and medical applications. It is highly soluble in water, producing a mildly acidic solution. Industrially, it serves as a nitrogen source in fertilizers, a flux in metalworking, and an electrolyte in dry cell batteries. In laboratories, it is used in buffer solutions and as a precipitating agent. Medically, ammonium chloride acts as an expectorant in cough medicines and helps treat metabolic alkalosis by increasing blood acidity. It also plays a role in yeast fermentation and food preservation. However, excessive exposure can irritate the respiratory tract, eyes, and skin, and ingestion may lead to nausea or metabolic disturbances. Proper handling and storage are essential due to its hygroscopic nature.

Ammonium chloride powder is an inorganic compound with the chemical formula NH4Cl, commonly produced as a byproduct in the alkali industry. This powder, as a common form of ammonium chloride, has a wide range of applications. The following is a detailed explanation of its use, aiming to comprehensively demonstrate its important role in different fields:
Ammonium chloride is an important raw material for manufacturing dry batteries and rechargeable batteries. In batteries, ammonium chloride serves as an electrolyte and participates in internal chemical reactions, providing continuous current to the battery. In addition, ammonium chloride can improve the discharge performance and cycle life of batteries, making them more stable and reliable. As an electroplating additive, it can improve the uniformity and density of the electroplating layer, enhance the corrosion resistance and hardness of the electroplating layer. Meanwhile, ammonium chloride can also serve as a flux for metal welding, reducing welding temperature and improving welding efficiency and quality. During the tanning process, it can be used as a tanning agent to bind with collagen fibers in leather, making it softer, tougher, and more durable. In addition, ammonium chloride can also be used as a dyeing aid to help dyes penetrate better into the fibers, improving dyeing effectiveness and fastness. It can also be used as an intermediate for various chemical products, such as manufacturing other ammonium salts, synthetic fibers, plastics, etc. It can also be used as a glass etchant and a chemical polishing agent for metal surfaces.
Industrial applications&Agricultural applications
During the glass etching process, ammonium chloride reacts with the silicate on the surface of the glass to form soluble silicate complexes, thereby achieving the etching of the glass. In the process of metal polishing, ammonium chloride, as one of the components in the polishing agent, can remove the oxide layer and dirt on the metal surface, making the metal surface smoother and brighter.
Ammonium chloride is also widely used in the agricultural field. As a physiologically acidic fertilizer, it contains high levels of nitrogen (about 24%~26%), which can provide the necessary nutrients for crops. However, due to the high chlorine content in ammonium chloride, it is not suitable for application on acidic and saline alkali soils, nor is it suitable for use as seed fertilizer, seedling fertilizer, or foliar fertilizer. However, the application of ammonium chloride in rice fields has high fertilizer efficiency and stability, because chlorine can inhibit nitrification in rice fields, promote the formation of rice stem fibers, increase toughness, and reduce rice lodging and pest invasion. In addition, ammonium chloride can also increase soil permeability, promote crop root growth and nutrient absorption.
Ammonium chloride also has important applications in the pharmaceutical field. As an expectorant and diuretic, it can help patients eliminate respiratory secretions and excess water, alleviate symptoms such as cough and edema. The expectorant effect of ammonium chloride is mainly achieved by stimulating the respiratory mucosa, making the sputum thin and easy to cough up. Meanwhile, ammonium chloride can also increase the excretion of urine, helping to eliminate excess water and toxins in the body. However, it should be noted that ammonium chloride has a certain degree of irritation, and it is necessary to follow medical advice and strictly control the dosage when using it.
Analytical Chemistry Applications
Ammonium chloride also has a wide range of applications in analytical chemistry. It can be used as an important raw material for preparing ammonia ammonium chloride buffer solutions, to adjust the pH value of the solution and maintain its stability. In addition, ammonium chloride can also be used as a supporting electrolyte in electrochemical analysis, an arc stabilizer for emission spectroscopy analysis, an interference inhibitor for atomic absorption spectroscopy analysis, and a testing reagent for synthetic fiber viscosity. These applications fully utilize the chemical properties and stability of ammonium chloride, making it play an irreplaceable role in the field of analytical chemistry.
Brewing and preservation: During the brewing process, ammonium chloride can be used as a disinfectant to effectively kill harmful microorganisms and ensure the hygiene quality of the wine. Meanwhile, ammonium chloride can also be used as a preservative to extend the shelf life of alcoholic beverages.
Photography and film: In the field of photography and film, ammonium chloride can be used as one of the components in developers and fixatives. It can help to better visualize and fix images on film or motion picture.
Rare element extraction: Ammonium chloride can also be used to extract rare elements. In certain chemical reactions, ammonium chloride can act as a reactant or extractant to help separate rare elements from complex mixtures.
Environmental protection field: With the increasing awareness of environmental protection, the application of ammonium chloride in the field of environmental protection has gradually attracted attention. It can be used as a flocculant or precipitant in wastewater treatment to help remove harmful substances such as suspended solids and heavy metal ions from wastewater.

Frequently Asked Questions
What is the use of ammonium chloride powder?
+
-
Ammonium chloride is used as an expectorant in cough medicine. Its expectorant action is caused by irritative action on the bronchial mucosa, which causes the production of excess respiratory tract fluid, which presumably is easier to cough up.
Is ammonium chloride safe to eat in licorice?
+
-
The ammonium chloride used to flavour salty liquorice is toxic. The long answer is that yes, it is toxic, but so are many other things that we routinely ingest (like alcohol). In small enough doses, the harm is negligible, relatively speaking.
Why do they put ammonium chloride in food?
+
-
Ammonium chloride as food additive E510
In the food industry, ammonium chloride is used as an acidity regulator and flavoring agent. It is approved as a food additive E510 in the EU and many other countries and is used in licorice products in particular.
Is ammonium a carcinogen?
+
-
How likely is ammonia to cause cancer? There is no evidence that ammonia causes cancer. The Department of Health and Human Services (DHHS), the EPA, and the International Agency for Research on Cancer (IARC), have not classified ammonia for carcinogenicity.
What does ammonia do to your brain?
+
-
Ammonia encourages impaired synaptic function in the aged brain, leading to memory loss. High levels of ammonium contribute to energy metabolism by inhibiting the tricarboxylic acid (TCA) cycle in neurons and glia, leading to a decrease in ATP production in mitochondria.
