It gives an obvious color change. It's preparation is simple and easy plus it's not harmful or hazardous. When starch is mixed with iodine in water, an intensely colored starch/iodine complex is formed. The complex is very useful for indicating redox titrations that involve iodine because the color change is very sharp. It can also be used as a general redox indicator: when there is excess oxidizing agent, the complex is blue; when there is excess reducing agent the color disappears.

What chemical indicator do you use for starch?
Starch is not the indicator. Iodine is the indicator of starch.
Which indicator would you use to test starches?
weee
Why starch is used as indicator in iodometric titration?
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 role of an indicator in the titration process?
indicator help us find out which molecules diffused and which didn't for ex: starch indicator indicate starch and glucose indicator indicate glucose.
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-)
For what purpose you use starch-iodine indicator paper?
it is used to indicate acidic radicals which reacts with the iodide solution.
What chemical indicator do you use for starch?
Starch is not the indicator. Iodine is the indicator of starch.
Is starch redox indicator?
Starch is a complexometric indicator.
Why chlorine turns moist starch iodide paper blue?
Chlorine oxidises Iodide to Iodine, which shows up as blue when complexed with starch.

What is the role of the indicator?
indicator help us find out find out which molecules diffused and which didn't.... for example: starch indicator indicate starch......and.......glucose indicator indicate glucose.
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
