KI can certainly be used to test for oxidizing agent on its own.

As what “dona” has stated, color will change from colourless (KI) to brown (I2).

Starch solution is used mainly like an indicator to enhance the visual confirmation.

hey. i recently found out about this website, and i feel that it is extremely helpful.

i was wondering, if aqueous potassium iodide by itself could be used to test for oxidising agents?
