The reaction oxidises at the positively charged electrode (the anode) and reduces at the negatively charged electrode (the cathode). This makes the 100ppm of free available chlorine (FAC) solution with changed chemical properties; a powerful but safe disinfectant and cleaning solution. That’s the ready to use solution as some of the models make a much higher concentration which is then diluted dispensed to 100ppm.
At the positive anode, the hydrogen and oxygen in the water reacts with the chlorine in the salt to produce the main, active substance called hypochlorous acid (HCIO), which is a powerful but safe disinfectant. This solution naturally wants to revert back to its original state by oxidising, for example, other organic matter. That’s part of its effectiveness.
At the negatively charged cathode the sodium and chlorine in the salt combines with the oxygen in the water to produce a mild form of sodium hypochlorite (NaClO). This is a gentle cleaning agent.
