It is a compound that is formed from the union of positively charged ions and negatively charged ions through ionic bonds, normally it is a compound that is quite soluble in water and its elements can be separated if it comes into contact with electricity. Common salt (sodium chloride) is one of the most used elements in world gastronomy, since it is used to flavor food, its chemical formula is NaCl.
One of the most important characteristics of this element is its ability to preserve food over time, avoiding its decomposition, which is why through history salt has been decisive in the life of manSince the first populations settled near the deposits in order to make the most of their properties, salt became so important in the world that during Roman times, soldiers were paid with salt, from there it also derives The term "salary", in addition to this, gained great relevance in the economic and social sphere, it was the most commercialized rock during the time of the Roman Empire, they were the ones who began with distribution by creating routes to facilitate transportation. The interest in dominating both the trade and the salt deposits was so great that it was the cause of wars and disputes between different states.
Over the years in Europe the collection of a special tax was implemented for the consumption and distribution of the compound, called "la gabelle", this payment was not seen with good eyes by the people since salt was considered of first necessity, therefore during the French Revolution eliminating this tax was one of the main objectives.
In order to obtain this compound, different methods can be applied, such as evaporating a brine (water with a high concentration of salt) applying heat, either natural or artificial, making the water evaporate and leaving the salt contained at the bottom. Also through the extraction of minerals in mines or salt flats (lakes where the presence of salt predominates).
