Question

Why do we boil the leaf in alcohol when we are testing it for starch​

Answer 1

Answer:

Hey mate here is your answer.

Explanation:

Thee hot water kills the leaf and the alcohol breaks down the chlorophyll,taking the green color out of the leaf.When you put iodine on the leaves,one of them will turn blue-black and the other will be a reddish-brown.Iodine is an indicator that it turns blue-black only in the presence of starch.

Boiling leaf in water helps to get rid of the waxy cuticle that blocks the entry of the iodine.
