Title: The nature of ammonium chloride and its application

description: This article will introduce the nature of ammonium chloride, chemical formula and its application in medicine, metallurgy, chemical industry and other fields.

keywords: ammonium chloride, chemical properties, applications, chemical formula

ammonium chloride is a common inorganic compounds, chemical formula NH4Cl. Its appearance is white crystals or granules with good solubility. Ammonium chloride is a volatile substance that can quickly lose moisture in the air. The nature of

ammonium chloride is mainly manifested in the following aspects:

1. acid and alkali: ammonium chloride in water can be decomposed into NH4 and Cl-ions, with acidic. But in a strong alkaline environment, it can play a buffering role, play a role in neutralizing acid and alkaline.

2. redox: under high temperature conditions, ammonium chloride can react with hydrogen to generate ammonia and ferric chloride. In addition, ammonium chloride can also react with copper nitrate to obtain nitrogen, water and ammonium hydrogen nitrate.

3. heavy metal ion adsorption: ammonium chloride can adsorb and precipitate copper, silver, collar and other heavy metal ions in water, and has a good decontamination function.

ammonium chloride is widely used in medicine, metallurgy, chemical industry and other fields. In the field of medicine, ammonium chloride can be used to treat coughs, colds, tracheitis and other diseases. In the field of metallurgy, ammonium chloride can be used as a passivator, degreaser and descaling agent in the steel industry. In the chemical industry, ammonium chloride can be used to make ammonia, polyurethane, cigarette paper and other products.

In short, ammonium chloride is a commonly used inorganic compound, with good acid-base neutralization, heavy metal adsorption and other characteristics, in medicine, metallurgy, chemical industry and other fields have a wide range of applications. The above is the nature of ammonium chloride and its application, I hope to help you.
