Starch is a complexometric indicator.
Starch indicator solution will remain its original color (usually colorless) in the absence of starch. Without starch present, there will be no color change observed when using starch indicator solution.
iodine.
the chemical indicator used is iodine and starch turns in dark blue colour ARE U HAPPIEE WID MA ANSWER ? THANKU
phenanthroline is used as a redox indicator
The indicator used to test for starch hydrolysis is iodine. Iodine reacts with starch to form a dark blue-black color, so if the color change is observed after treating a sample with an amylase (enzyme that breaks down starch), it indicates that starch has been hydrolyzed.
Starch solution is used as an indicator in redox titrations to detect the endpoint of the titration. It forms a complex with triiodide ions to produce a blue-black color when excess iodine is present, indicating that the reaction has reached completion. This helps in determining the equivalence point of the titration.
Starch is not the indicator. Iodine is the indicator of starch.
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
Starch indicator solution will remain its original color (usually colorless) in the absence of starch. Without starch present, there will be no color change observed when using starch indicator solution.
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.
If you are looking at a iodide to iodine redox titration, the solution would turn yellow instead of blue/black. The blue/black color of the iodine-starch complex is very intense and so the end-point is sharper. Without the starch, the endpoint, when the first yellow from the formation of iodine I2, appears, is less sharp and is harder to see.
Iodine is an indicator for starch. The reaction between iodine and starch causes a color change from brown/orange to blue/black.
No indicator is needed in redox titration because the endpoint of the titration is determined by a change in the appearance of the titrand. This change can be detected visually, such as a color change, indicating the completion of the reaction without the need for an indicator.

iodine.
Litmus milk medium is skim milk to which the dye litmus has been added. Litmus is both a pH indicator and a redox indicator. It is pink at pH < 4.5, purple in middle pH's and blue at pH > 8.3. As a redox dye, in the absence of oxygen (reduced state) it's colorless (white due to milk) and in the presence of oxygen (oxidized state) it is purple.
Iodine is an indicator for starch. It turns blue-black in the presence of starch, making it a useful tool for detecting the presence of starchy substances in solutions or biological samples.
