Decribe the results of what happen when idoine is add to a potatoe and viewed under a microscope in comparison to the results of just water added to a potatoe under a microscope.

Solution

Answer:

Starch can be identified by the iodine test. Few drops of iodine solution are added to a starch containing sample or to the substance suspected of containing starch. If starch is present, the substance will turn blue-black in the area where the iodine solution touches it, amd will not change its colour if starch is absent.

Substances with very small amounts of starch will turn faint blue or greenish instead of blue-black. Many materials of biological origin have high starch content. These materials can be identified with the iodine test.

When a drop of iodine is added to a potato, it will turn blue black concluding for the presence of large amount of starch.

When a drop of water is added to a potato, it will not undergo a change in colour.
