Table salt, also known as sodium chloride (NaCl), is a crystalline compound that is commonly used as a seasoning and preservative in food, as well as for various other purposes.

Table salt can be obtained from both natural sources and through industrial processes. It is often extracted from salt mines, sea salt through evaporation of seawater, or through solution mining of underground salt deposits. The extracted salt is purified, processed, and sometimes iodized (with iodine added) for nutritional purposes.

Table salt is a ubiquitous and versatile ingredient in cooking and food preservation, as well as an important component of human nutrition and various industrial processes. Its importance in these different areas makes it a staple in most households.
