I made the starch indicator with 2 grams of soluble starch in 500 mL of heated water, I used about 1-2 mL for the titration. The analyte consisted of a 10 mL aliquot of dilute bleach (10 mL pure bleach in 250 mL water), 1 mL 3 M H2SO4, and 2 grams of excess KI. The titration required about 67 mL...

I am performing a REDOX titration of a diluted bleach sample in my analytical chemistry class. I am using sodium thiosulfate as the titrant to determine the amount of sodium hypochlorite ion in solution. I am using a starch indicator, which is supposed to turn from blue to colorless at the...
