Chemical Properties and Common Uses of Sodium Chloride

Common Industrial Uses and Products that Include Sodium Chloride

  • Sodium chloride, commonly known as table salt, is used in the food industry as a flavor enhancer and preservative. It is also used in the production of processed foods such as cheese, bread, and canned vegetables.
  • In the chemical industry, sodium chloride is used in the production of chlorine and caustic soda, which are used to make a variety of products including paper, textiles, and detergents.
  • Sodium chloride is used in the pharmaceutical industry as a saline solution for intravenous injections and as a component in the production of various medications.
  • In the oil and gas industry, sodium chloride is used as a drilling fluid to control the pressure and temperature of the wellbore during drilling operations.

How Sodium Chloride is Produced

Sodium chloride is primarily produced through the evaporation of seawater or brine from underground salt deposits. The process involves pumping seawater or brine into large evaporation ponds where the water is allowed to evaporate, leaving behind a concentrated solution of sodium chloride.

The concentrated solution is then further processed to remove impurities such as calcium and magnesium, and the resulting sodium chloride is dried and packaged for distribution.

When Sodium Chloride was First Discovered and Made Commercially Available

Sodium chloride has been used by humans for thousands of years, with evidence of its use dating back to ancient civilizations such as the Egyptians and Greeks.

The commercial production of sodium chloride began in the 18th century, with the development of large-scale salt mining operations in Europe and North America. These operations allowed for the production of large quantities of salt, which was used for a variety of purposes including food preservation and the production of soap and glass.

Today, sodium chloride is one of the most widely produced chemicals in the world, with global production exceeding 300 million tons per year.

Introduction to Sodium Chloride

Sodium Chloride, commonly known as table salt, is a chemical compound with the formula NaCl. It is an ionic compound consisting of positively charged sodium ions and negatively charged chloride ions. Sodium Chloride is an essential nutrient required by the human body, and it is also widely used in various industries, including food, chemical, and pharmaceutical.

Technical Properties of Sodium Chloride

Sodium Chloride is a white crystalline solid that is highly soluble in water and insoluble in most organic solvents. It has a high melting point of 801°C and a boiling point of 1413°C. Sodium Chloride is a good conductor of electricity when dissolved in water due to the presence of ions. It has a density of 2.165 g/cm³ and a molar mass of 58.44 g/mol.

Chemical Formula and Structure of Sodium Chloride

The chemical formula of Sodium Chloride is NaCl, which means it consists of one sodium ion (Na+) and one chloride ion (Cl-) held together by an ionic bond. The crystal structure of Sodium Chloride is a face-centered cubic lattice, where each sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by six sodium ions.
