Starch is not used in order to do this. This is because starch is able to form a complex along with the iodine and this is the indicator.

What is the function of starch solution in the redox titration?
It is used as indicator for the endpoint of a Iodometric (redox) titration: it gives a bluish grey to black color with very minute excess of Iodine-iodide ions (I3-)
What is hypo solution used in chemistry for iodometric titration?
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
Why is phenolphthalein used in the titration experiment?
it is used as an acid-base indicator
What is meant by External Indicator used in titration?
Indicators used outside the titration flask are termed as external indicators. A very commonly used external indicator is potassium ferricyanide
How is an indicator used to determine the pH of a solution?
Iodine solution is an efficient indicator for starch. It will go from a light brown colour to a black colour if starch is present and will stay light brown if no starch is present. Hope this Helps!

The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
Why is phenolphthalein is used in titration experiment?
it is used as an acid-base indicator
Which indicator is used in titration of naoh and h2so4?
Methyl orange
Why phenolphthalein used in titration?
it acts as acid base indicator
What color does the indicator turn when starch is present?
Iodine is used to indicate whether starch is present in a solution. If starch IS present, the indicator will turn dark blue/black. Iodine is used to indicate whether starch is present in a solution. If starch IS present, the indicator will turn dark blue/black. FOR WHAT PURPOSE WE USE STARCH-IODINE INDICATOR PAPER
Why is starch solution used as indicator in Sodium thiosulphate Iodine titrations instead of phenolphthalein indicator?
Phenolphthalein is an acid base indicator - it does not show the end-point in a thiosulfate type titration. Starch gives a very sharp end-point from a blue-black to colorless end-point when titrating iodine with thiosulfate. Phenolphthalein would just not detect this change.
What are different types of indicator used in titration?
phenolphthalein is one i know.
