Heating copper sulfate pentahydrate to release the water and observe the color change. Kerry and Eileen are two of my better students this semester in another very good class.
Small world: Eileen was talking to me about art restoration and I mentioned that my brother is a curator at an art museum. Turns out she knows him, having worked at the same museum a couple of years ago, helping to keep the paintings clean. Imagine that.
