NaCl

NaCl or Sodium Chloride is a chemical compound that is commonly known as table salt. It is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.

Chemical Properties

Sodium chloride is an ionic compound, which means it is made up of charged ions that have bonded together. In the case of NaCl, the sodium ion (Na+) and the chloride ion (Cl-) have a strong electrostatic attraction that holds them together. This results in a crystal lattice structure, which gives NaCl its characteristic cubic shape.

Physical Properties

Sodium chloride is a white crystalline solid at room temperature. It is highly soluble in water, and its solubility increases with temperature. It has a melting point of 801 degrees Celsius and a boiling point of 1,413 degrees Celsius.

Uses

Sodium chloride is most commonly used as a seasoning and preservative in food. It is also used in industrial applications, such as the production of chlorine and sodium hydroxide, and in the manufacture of polyvinyl chloride (PVC), paper, and textiles.

Health Effects

While sodium chloride is necessary for human health, excessive consumption can lead to health problems such as high blood pressure, heart disease, and stroke. The World Health Organization recommends a maximum intake of 5 grams of salt per day for adults.
