15 Minutes Later - I was answering the questions in the lab guide when I noticed something about the bag. When I looked at it carefully, parts of it were turning purple. I lifted the bag out of the beaker and could see that the beaker was still the same color orange as when we started, but the white cornstarch solution was purple. It was amazing, and I knew exactly what had happened! **Explain what happened in the experiment. Use the following words in your explanation: indicator, concentration, semipermeable, and diffusion.**
