Vedclass · Answer

(B) Starch is used as an indicator in iodometric titration because it forms a deep blue-colored complex with $I_2$ (iodine). Starch is indeed a polysaccharide,but this chemical property (being a polysaccharide) is not the reason why it acts as an indicator in this specific titration. Therefore,both statements are correct,but the Reason is not the correct explanation for the Assertion.

Assertion : In the iodometric titration,starch is used as an indicator.
