Starch indicator

Starch indicator

Starch is often used in chemistry as an indicator for redox titrations where iodine is present. Starch forms a very dark blue-black complex with iodine. The indicator is not affected by the presence of iodide (I-).

Starch indicator solutions may be prepared in the laboratory. Alternatively, commercially available preparations are available. [E.g. from [http://fscimage.fishersci.com/msds/40185.htm Fisher Scientific] .]
