A change of color to a blue-black or purple color suggests that starch is present. If there is no change in color, this suggests no starch is detectable. Note the change of the iodine to black on the potato (right) but not the apple (left). (10% Tincture of iodine.) Potato contains starch, but apple does not.
A bluish-black color indicates the presence of iodine in the starch solution. It is thought that the iodine fits inside the coils of amylose.A 0.3% w/w solution is the standard concentration for a dilute starch indicator solution. need the reaction equation(s) between Iodine and starch as one part of my experiment report.I will need source for your answer.Thanks!
