Saline solution contains the several kinds of ions such as Na +, H -, when electrolysis, under a certain voltage, as a result of the movement of ions in the electrolyte solution and electrode reaction, the conductive effect occurs, then CL -, OH - such as negative ion to the anode, and positive ions such as Na +, H + to the cathode, and the corresponding electrode discharge occurs, thus carries on the REDOX reaction, the corresponding material production.
Electrode reaction：
anode： 2Cl- - 2e → Cl2；
cathode： 2H+ + 2e → H2；
Solution reaction:
2NaOH + Cl2 → NaCl + NaClO + H2O
Overall reaction as follow：
Na Cl + H2O + DC →NaClO + H2↑
