electolysis of brine

The salt solution contains several ions such as Na+, H-, etc. According to the electrolysis theory, when the electrode is inserted, under a certain voltage, the electrolyte solution conducts electricity due to the movement of ions and the electrode reaction. At this time, Cl-, OH- Negative ions move to the anode, while positive ions such as Na+ and H+ move to the cathode, and discharge occurs on the corresponding electrodes, so as to carry out redox reactions and produce corresponding substances.

Electrolysis of sodium chloride solution reaction equation：

2NaCl+2H2O=2NaOH+2H2↑+2Cl2↑.

When electrolysis without diaphragm is used in industry, sodium chloride and sodium hypochlorite will be generated due to the contact of chlorine ions or chlorine gas with sodium hydroxide. In electrolysis of brine without diaphragm, the total equation of the solution is NaCl+H2O+2F→NaClO+H2↑
