Currently doing a practical report on an Indirect titration to determine the concentration of a bleach sample. But iodide was used to convert the hypochlorite into chloride. And I wanted to know the effect of the reaction when using starch as an indicator for the excess amount of iodide.

My main question: Is there a chance that iodine molecules can get stuck in the starch iodide complex? And if they do, are they able to react with other chemicals.

As this would be a error that would occur in each trial but to a different extent. For determining the end-point of the reaction between iodide and our standard solution of sodium thiosulfate.

This is wrong. It get converted to  chloride.

The iodometric titration is a common method. The starch didnt disturb it.
