The main components of salt
The main component of salt is sodium chloride (NaCl), which is a compound composed of sodium ions and chloride ions. Sodium chloride is one of the most common salt substances on the earth, which exists widely in natural seawater.
The salty taste of sodium chloride comes from the interaction between sodium ion and chloride ion. When sodium ions and chloride ions are dissolved in water, they will form positively charged sodium ions and negatively charged chloride ions, and the interaction between these ions will produce salty taste.
In addition to sodium chloride, salt substances may contain other impurities and minerals. For example, well salt and mineral salt may contain minerals such as calcium, magnesium and iron, while sea salt may contain organic substances such as algae and marine microorganisms. The existence of these impurities and minerals makes different kinds of salts have different physical and chemical properties.
