13. «Common Salt»
Common salt, also known as sodium chloride (NaCl), is a naturally occurring mineral that is essential for human life. It is commonly used as a seasoning for food, a preservative, and in various industrial applications.
Salt is found in large deposits around the world, both in underground mines and in sea water. In fact, sea water is approximately 3% salt by weight. Salt is also an important component of many rock formations and is often mined from ancient seabeds.
One of the most important properties of salt is its ability to dissolve in water. When salt dissolves, it breaks down into its two components, sodium and chloride ions. These ions are essential for various bodily functions, such as nerve and muscle function, and fluid balance.
In addition to its biological importance, salt has been used for thousands of years for its various properties. It was once used as a form of currency, and in some cultures, it was even considered to have mystical properties.
Today, salt is used in many industries, such as food production, chemical manufacturing, and water treatment. It is also used to melt ice on roads and sidewalks during the winter.
Despite its many uses, it is important to consume salt in moderation. High salt intake has been linked to various health problems, such as high blood pressure and heart disease. Therefore, it is recommended to limit salt intake to no more than 2,300 milligrams per day.
Overall, common salt is a versatile and important substance with a long history of use. Its importance in human life and various industries cannot be overstated.
