Question

to show that saliva converts starch food into sugar​

Answer 1

Answer:

Experiment for the saliva concerts starch into sugar

Explanation:

Take two test tubes. Label them A and B. In test tube A put one teaspoonful of boiled

rice; in test tube B keep one teaspoonful of boiled rice after chewing it for 3-5 minutes.

Add 3-4 ml of water in both the test tubes. Now pour 2-3 drops of a chemical dilute iodine solution in each

test tube and observe.

There is a colour change in test A because the boiled rice contained starch.

And in test tube B the saliva converts starch into sugar. So there is no colour change in test tube B
