Answer 1

Answer:

The starch present in the flour traps the iodine inside its structure and hence blue colour is observed. Saliva has amylase enzyme in it which dissolves starch to simpler sugars and hence the solution with saliva in it could not show blue colour due to lack of starch.

Answer 2

Experiment to show the effect of saliva on starch

Two test tubes were taken and were labeled A and B.

In test tube A one teaspoon full of boiled rice was kept.

In test tube B one teaspoon full of boiled rice which were chewed for 3-5 minutes were kept.

3-4 ml of water was added to both the tubes.

Then 2-3 drops of iodine solution was added to both test tubes A and B.
