Question

One spoonful wheat flour is taken and mixed with 3 spoonful water in a glass. After 5 minutes iodine solution was added. Write its observation and inference

Answer 1

Answer:

The enzyme salivary amylase which is present in the saliva will convert more overly they'll break down the large starch molecules into the smaller forms of sugars. This action was taken place in the 2nd test tube where saliva was added so the color of the solution didn't change to blue-black as it changed in the 1st and 3rd test tube.

this is inference !! hope it helps

the 2nd test tube where there was only water, flour, saliva when the iodine solution was added the color of the solution didn't turn blue-black due to the action of the saliva.

3. As same as the 1st test tube the 3rd test tube also turned to blue-black ! this is observation
