Iodine Indicator is a preparation with good keeping qualities, but unlike starch is readily soluble in cold water to give a clear colorless solution.

Iodine Indicator is a white powder which is completely stable and, as it can be stored indefinitely, it offers a considerable advantage over starch solution which normally has to be freshly prepared.

The indicator forms a blue complex with Iodine and can be used instead of starch in all titrations: 0.2-0.5 grams being added in place of starch to the contents of the titration vessel, after which the titration is completed in the usual manner.
