The solutions used typically included hydrogen peroxide, potassium iodate, and manganese sulfate, which reacted to produce starch-iodine complex changes visible in color. The experiment ...

The different lengths of time needed to achieve the starch/iodine complex shows the effect of temperature on reaction rates ... Have students prepare to time each reaction from the instant of mixing ...

forming a starch-iodine complex that creates the visible colour changes. The timing of the colour shifts depends on the concentrations of the reactants and the reaction conditions, allowing ...

This glucose is: After a few minutes, the parts of the leaf that contain starch turn the iodine from brown to blue/black. Variegated leaves have green parts (where the cells contain chlorophyll ...
