WebBetween a pH of 6.5 and 8.5 this dissociation is incomplete and both HOCl and OCl- species are present to some extent. Below a pH of 6.5, no dissociation of HOCl occurs, while above a pH of 8.5, complete dissociation to OCl- occurs. As the germicidal effects of HOCl is much higher than that of OCl-, chlorination at a lower pH is preferred. Web15 hours ago · This may arise from an increase in solution pH to 8.4. At higher pH, the OCl â€“ content of the solution increases and HOCl decreases. OCl â€“ is not as reactive as HOCl (Xu et al., 2024). Thus, the decrease of HOCl content at higher pH accounts for the reduced DHHB degradation rate. porcelain-faced woman
