11. Benedict’s Solution is a known indicator of glucose. The chemical starts blue, but turns
orange when introduced to glucose. Knowing this, a scientist runs the following
experiment:
The scientist places pure glucose sugar in a baggie with water, creating a clear liquid, and ties it
off. She then combines Benedict’s Solution and water in a beaker, creating a light blue liquid.
Finally, she places the baggie in the beaker. After thirty minutes she observes that the liquid in
