A 25.0-mL sample of household bleach was diluted to 500mL in a volumetric flask. An unmeasured surplus of KI was added to a 20.00-mL aliquot of the diluted sample the iodine liberated in the reaction OCl- + 2I- + 2H = I2 + Cl- + H2O needed 34.50mL of 0.0409 M Na2S2O3. Compute the weight-volume percentage of NaOCl in the sample.
