Ammonium chloride is a highly versatile compound that is widely used in various industries. This compound is also known by the chemical formula NH4Cl, and it is a white crystalline salt that is highly soluble in water. The compound has a pungent odor that is often described as similar to that of ammonia.
Ammonium chloride is used in a variety of applications, including as a food additive, a fertiliser, a flavouring agent, as well as in the production of batteries, textiles and dry cell batteries. Interestingly, it has a unique effect when it is inhaled or ingested, as it produces a cooling sensation in the mouth and throat.
Properties
Ammonium chloride is a very small molecule, with a molecular weight of only 53.49 g/mol. The melting point of ammonium chloride is 338°C, and the boiling point is about 520°C. When ammonium chloride is exposed to air, it can absorb moisture and become damp, which can cause it to clump together.
As mentioned earlier, ammonium chloride is highly soluble in water, and it dissolves readily in acids, such as hydrochloric acid. It is also slightly soluble in alcohol and glycerol, but it is not soluble in ether.
Uses
Food Additive
Ammonium chloride is used as a food additive to control the pH of foods, especially in baking powders, bread dough, and certain types of chocolates. It is also used as a flavouring agent for salty liquorice, as a colour fixative in some textiles and to enhance the flavour of meat and poultry.
Fertiliser
Ammonium chloride is also used as a fertiliser in agriculture. This compound provides plants with two essential nutrients, nitrogen and chloride, which help the plants to grow and develop. Ammonium chloride is often used in agricultural soils that are depleted in these essential nutrients.
Production of batteries
Ammonium chloride is used in the production of dry cell batteries, in particular, manganese-ammonium-chloride galvanic cells. The electrolyte in these cells is created from ammonium chloride and manganese chloride, which react in the anode compartment of the cell.
Textiles
Ammonium chloride is a popular mordant in dyeing textiles. A mordant is a chemical substance that helps to fix dye onto a fabric by increasing its chemical bonding. In the textile industry, ammonium chloride is used to dye wool and cotton fabrics.
In Conclusion
In conclusion, ammonium chloride is an incredibly versatile compound that is used in a range of industries. Its unique properties make it ideal for a variety of applications, including as a food additive, fertiliser, flavouring agent, and in the production of batteries and textiles. Its cooling effect also makes it a popular ingredient in cough drops and lozenges.
