Titanium electrode for swimming pool
|
Sodium hypochlorite generator is a set of device that generates sodium hypochlorite solution after low-concentration salt water undergoes electrochemical reaction through an energized electrode. The total response is expressed as follows: NaCl + H2O → NaClO + H2 ↑ Electrode reaction: Anode: 2Cl--2e → Cl2 Cathode: 2H + + 2e → H2 Solution reaction: 2NaOH + Cl2 → NaCl + NaClO + H2 |
