The level of underchloric ,acid, will decrease when the pH value is higher. With a pH value of 6 the level of underchloric ,acid, is 80%, whereass the concentration of hypochlorite ions is 20%. When the pH value is 8, this is the other way around. When the pH value is 7,5, concentrations of underchloric ,acid, and hypochlorite ions are equally high.
