WebZenu Destroyer of Worlds (AK) bleach is basically a solution of sodium HypoChlorite, or NaClO. This is a salt that contains the anion of the weak acid HClO, hypochlorous acid, and the cation of the strong base, NaOH. Because NaOH is a strong base, it fully dissociates into Na+ ions and OH- ions.
