WebThis 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. However, the HClO is weak and does not fully dissociate. Therefore, there is more OH- ions inside the solution and less H+ ions. WebIn chemistry, pH is a scale that describes how acidic or basic a water solution is. A pH level of 7.0 is neutral and represents the middle of the scale. Acidic solutions have a pH value lower than 7, and basic or alkaline solutions have a pH level higher than 7. btstack github
