Verified answer
1. 2 test tubes labeled A and B are taken, where tube A contains 1 tsp of boiled rice and tube B has 1 tsp of rice which has been chewed for 3-5 mins.4 ml water is added to both the test tubes and then 2-3 drops of iodine solution is also added to each test tube.The color in the tube A changes to bluish-black color, whereas the color in the tube B remains unchanged.This is because the rice in the tube B has been chewed and the saliva has acted on it and broken down the starch molecules into smaller sugar particles.
