The main component of salt is sodium chloride (NaCl), and the salt solution is mainly composed of sodium chloride solution. We think that the mixture has no chemical formula, so the salt solution has no chemical formula. We can only say that the salt solution is sodium chloride solution.

In industry, NaOH, Cl2 and H2 are produced by electrolyzing saturated NaCl solution, and a series of chemical products are produced from this, which is called chlor-alkali industry. Chlor-alkali industry is one of the most basic chemical industries, and its products are widely used in light industry, textile, metallurgy, petrochemical industry and public utilities.

What does a mixture usually mean:

A mixture is a mixture of two or more substances. The mixture has no fixed chemical formula, no fixed components and properties, and there is no chemical reaction between the various components that make up the mixture, so that they maintain their original properties. The substances contained in the mixture can be separated by physical methods. Not made up of chemical synthesis.

For example, the air contains oxygen O2, nitrogen N2, rare gas, carbon dioxide CO2 and other gases and impurities; Petroleum (crude oil), natural water, solution, muddy water, milk, alloy, fossil fuel (coal, natural gas, petroleum), seawater, brine, etc. Contains all kinds of organic substances.
