Vedclass · Answer

(C) The starch-iodide paper is primarily used to detect the presence of oxidizing agents. When an oxidizing agent reacts with the iodide ions $(I^-)$ present in the paper,it oxidizes them to iodine $(I_2)$. The liberated iodine then reacts with the starch to form a blue-colored complex. Therefore,it is used for the test of oxidizing agents.
