WebDETERMINATION OF A HYPOCHLORITE SAMPLE I 3-is generated using ClO-in a 1 to 1 mole ratio and is then reacted with the standardized thiosulfate solution. The following two reactions govern the iodometric titration of hypochlorite: In the reaction two thiosulfate ions (S 2 O 3 2-) react for every hypochlorite (ClO-) ion reacted. WebIodimetric titration is an indirect titration method. Iodometric titration is a direct titration method. Two redox reactions occur in this titration.
