Extraction of brine The rock salt can be dissolved when water is pumped down onto the solid mineral. An example is the electrolysis of an aqueous sodium chloride solution—although oxygen should be produced at the anode based on its potential, bubble overpotential causes chlorine to be produced instead, which allows the easy industrial production of chlorine and sodium hydroxide by electrolysis. Sodium Hypochlorite producing line including: Brine purification system, Electrolyzing. The electrolysis of brine solution can be given as follow: NaCl + 2H2O→ H2 + Cl2 + 2NaOH Here chlorine will react to give NaOCl (sodium chlorate) gas. Electrolysis of brine. Though treatment sessions are typically short, your first treatment may only destroy 15 to 50 percent of your unwanted hair [source: Leortec ]. The high oxidising potential of elemental chlorine led to the development of commercial bleaches and disinfectants, and a reagent for many processes in the chemical industry.
