Alice Lyons · Answer 1

starch indicator will not change its color

Explanation:

if starch indicator is added to the water solution it will change its amber colour if starch is added in the water solution and vice versa.

Gideon Maxwell · Answer 2

The starch indicator will take on a color between blue and black.

Explanation:

When you put a piece of potato in a glass of water, the starch in the potato will start to come out of the potato and stay in the water. After an hour it is likely that all of the potato starch is in the water.

When the starch comes in contact with the water in the cup, it starts to occupy the spaces between the water molecules, which means that we have a solution (starch + water), when the starch indicator is added to this solution, it reacts with the starch molecules and takes on a color between blue and black.
