Brine salt water, especially if popular salt i.e, sodium chloride, is a highly concentrated water solution. The aqueous solution of evaporite deposits, such as those found in salt domes, will form brine. A salt dome is a geological system where, due to the great weight of this overlying rock and sediment, very dense layers of comparatively “plastic” salt drained upward through the bedrock.
The electrolysis process requires the use of an electric current to bring about a chemical transition and the development of new chemicals. A large-scale method used to produce chlorine from salt is the electrolysis of brine. Two other valuable chemicals, sodium hydroxide (NaOH) and hydrogen, are obtained during the process (H2).
