CAS No. 756-13-8: An Overview of the Chemical Properties and Uses of Sodium Chloride
Abstract
Sodium chloride, also known as table salt, is a chemical compound with the CAS registry number 756-13-8. The compound is an ionic halide composed of one sodium cation and one chloride anion. Sodium chloride is an essential mineral for human life and is used in a wide range of industries, including food processing, chemical production, and pharmaceuticals. This paper provides an overview of the chemical properties and uses of sodium chloride.
Introduction
Sodium chloride, commonly known as table salt, is an essential mineral for human life. It is composed of one sodium cation and one chloride anion, and has the chemical formula NaCl. The compound is a colorless solid with a cubic crystal structure, and has a melting point of 801°C. Sodium chloride is highly soluble in water and is found naturally in the oceans and in underground deposits. It is also found in many foods, including meats, vegetables, and dairy products.
Chemical Properties
Sodium chloride is an ionic halide composed of one sodium cation (Na+) and one chloride anion (Cl-). The compound is highly soluble in water, but is insoluble in non-polar solvents such as alcohol and ether. The compound is also hygroscopic, meaning that it absorbs moisture from the air. At room temperature, sodium chloride has a cubic crystal structure, with each Na+ ion surrounded by six Cl- ions, and vice versa.
Uses
Sodium chloride has a wide range of uses, both industrial and non-industrial. In the food industry, it is used as a preservative, flavor enhancer, and anti-caking agent. It is also used in the chemical industry for the production of detergents, plastics, and other synthetic materials. In the pharmaceutical industry, it is used as a source of sodium ions in drug formulations, as well as in the production of many antibiotics.
Conclusion
Sodium chloride, also known as table salt, is an essential mineral for human life. The compound is composed of one sodium cation and one chloride anion, and has the chemical formula NaCl. It is highly soluble in water and is used in a wide range of industries, including food processing, chemical production, and pharmaceuticals.
