For the second day of our “Where’s the Evidence?” lab, students combined copper sulfate with sodium carbonate. The two compounds were mixed with water and then combined in a test tube, producing a chemical reaction. The copper atom replaced the two sodium atoms, switching places and producing two new compounds: copper carbonate and sodium sulfate. The result was a cloudy blue liquid called “the blue goo.”
