@mrfarabaugh@wnchem Yes, Lee did this demo. Then, Jeff Bracken and Jesse Bernstein put this into a lab experiment investigation that involves several companies that might have polluted a body of water. This lab appears in our Lab Manual. Great lab for learning about SDSheets and their information.
@ChemistryWorld I would like to know what is the definition of an AP Chemistry Expert and who does the designation of such an expert! Is this a self-proclamation?
@Agchem250@wnchem Make certain that students move the burner back and forth to remove all of the water. Students should notice the change in color from blue to white solid.
@chemmastercorey@wnchem Rehydrating reall emphasizes just how much energy was needed to dehydrate the copper sulfate pentahydrate. Make certain that students know to be careful while holding the test tube when water is added. Plus, the blue color returns.

@wnchem When living outside Cleveland I made maple syrup from the sap from the sugar maple trees that lined our driveway. Energy intensive but the end result was delicious! Yummmmmm!
@adchempages Actually, Rf values can be used to rule out substances that are similar in color. If the Rf values differed considerably from one another in the same solvent then the two substances are not the same despite their similar colors. Works for both inorganic and organic compounds.
@pricepd Paul, did something similar a long time ago with a student as a research project. We used pipets that were cut up into micro scale and also used a 9-V battery. Pretty neat.
