Sodium Hypochlorite compared to Calcium

2019-10-28  When released to air, sodium and calcium hypochlorite are broken down by sunlight and compounds commonly found in the air. In water and soil, sodium and calcium hypochlorite separate into sodium, calcium and hypochlorite ions (an ion is an electrically charged atom or molecule). These ions may react with other substances found in the water.
