The following method is reported in Standard Methods for the Examination of Water and Wastewater for the analysis of sodium hypochlorite (NaOCI) in bleach. . a 20.00 mL sample of bleach is diluted to 100.0 mL. a 25.00 mL aliquot of the diluted sample is then transferred into a flask and treated with an excess acidic iodide solution. the iodine thus formed, is titrated with a standard thiosulfate solution. The chemistry is outlined below (unbalanced equations): Excess iodide is reacted with the analyte in an acidic solution. OCT + I + H CI+ 1 + HO The resulting iodine (1) is then titrated with a standardized solution of sodium thiosulfate. SO3 + 1 S40 + I If 12.62 mL of a 0.00400 N thiosulfate solution was required to reach the end point, what is the concentration of the original bleach solution as wt% and ppm as Cl?
