All the alpha amylase molecules should rupture . Boil water and then add to the boiling water required starch. Make sure that the starch is alpha and not beta amylase. Use freshly prepared starch solution for iodometric titrations. --unnikrishnan
Starch is not the indicator. Iodine is the indicator of starch.
Iodine is an indicator for starch. The reaction between iodine and starch causes a color change from brown/orange to blue/black.
Iodine turns it purple in the presence of starch. :D~PiNkBuN17 Aka Aisha
Starch indicator should not be added at the beginning of an iodometry titration because iodine can form a complex with the starch, resulting in a blue-black color that can obscure the endpoint. It is best to add the starch indicator near the endpoint, when the iodine is almost completely reacted, to help visualize the color change.
Starch is used as an indicator in iodometric titration because it forms a blue color complex with iodine. This helps in visually detecting the endpoint of the titration, which is when all the iodine has been reacted with the analyte. The appearance of the blue color indicates that the reaction is complete.
Starch is a complexometric indicator.
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.

iodine.
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.
the chemical indicator used is iodine and starch turns in dark blue colour ARE U HAPPIEE WID MA ANSWER ? THANKU
Iodine is used as an indicator for starch. When a substance has iodine added to it, then it will turn into a dark blue color. This is a sign that the substance indeed has starch in it.
