A 24.93-mL sample of liquid bleach (contains NaOCl;74.44g/mol ) was diluted to a final volume of 1,785.1 mL. A 38.77-mL aliquot of the diluted sample was transferred into an Erlenmeyer flask and treated with excess KI to oxidize the OClto Cl2 and producing I2. The liberated I2 intermediate was determined by titrating with 0.1717MNa2S2O3 and required 16.62mL to reach a starch indicator endpoint. A blank correction of 0.03mL was required. Calculate the %w/vNaOCl in the original sample of bleach. Provide your answer to two places after the decimal point and without units. Rections: 2OCl+2I+4H+I2+Cl2+2H2OI2+2S2O322I+S4O62 Type your
