- You wish to add enough NaOCl (sodium hypochlorite) to a 150 m³ swimming pool to provide a dose of 5.0 mg/L TOTOCI as Cl2. (a) How much NaOCI (kg) should you add? (Note: the equivalent weight of NaOCl is based on the reaction: NaOCl + 2H + 2 e→CI + Na +H₂O.) (10 pts) (atomic weight: Na 23, O 16, C1 35.5) (b) The pH in the pool after the NaOCl addition is 8.67. To improve disinfection, you want at least 90% of the TOTOCI to be in the form of HOCI (pKa 7.53). Assuming that HOCI/OCI is the only weak acid/base group in solution, what volume (L) of 10 N HCl must be added to achieve the goal?
