A sample of bleach has a content of about 2.13% (w/v) in “active chlorine”. For perform its analysis by redox volumetry and using a thiosulfate solution of sodium, how much of this sample would be needed to prepare, in a volumetric flask, 500 mL of a 0.0301 M solution in NaClO ? A 25.00 ml aliquot of the solution contained in the flask, was titrated using a standardized 0.0557 M sodium thiosulfate solution. What was the volume of titrant spent? Data: MM NaClO = 74.45 g/mol; MM Cl2 = 70.90 g/mol
