I have been mulling over these ideas for many years and I have never seen anyone address the imprope... Usually, sodium hypochlorite (NaOCl) is used, rather than calcium hypochlorite [Ca(OCl)2], because calcium hypochlorite is more costly, causes calcium sludge, and is more dangerous to handle. Bulk solution of sodium hypochlorite in water, usually 10.0% - 12.5% available chlorine. A comparison of commercial sodium hypochlorite (NaOCl) and sodium dichloroisocyanurate (NaDCC) products was made. You can mix it with water to make liquid bleach (which you can use to purify water). NaDCC (Sodium dichloroisocyanurate). A popular choice for shock â granular chlorine, in particular calcium hypochlorite. Sodium hypochlorite is a liquid and can be added directly to water for disinfection. Sodium hypochlorite (commonly known in a dilute solution as bleach) is a chemical compound with the formula NaOCl or NaClO, comprising a sodium cation (Na +) and a hypochlorite anion (OCl â or ClO âIt may also be viewed as the sodium salt of hypochlorous acid.The anhydrous compound is unstable and may decompose explosively. For a pool starting at 150 ppm CH, adding 10 ppm available chlorine daily with cal hypo would cause the CH in the pool water to reach 1,006 ppm in 107 days. Large quantities of chlorine can be harmful. f Inhaling Sodium Hypochlorite can irritate the lungs. f Exposure to Sodium Hypochlorite can cause headache, dizziness, nausea and vomiting.
