Description In this experiment, you will explore the reaction between CoCl2(C3H8O)2 and water to form Co(H2O)62+. Keep good notes of all procedures performed and all observations. Look at the solution of CoCl2(C3H8O)2 in isopropanol and the solution of Co(H2O)62+ in water and note the color of each under a section headed “Observations”. Watch the following preparations on video: Use a graduated cylinder to measure 10.0 mL of 0.176 M CoCl2(C3H8O)2 into a 50 mL Erlenmeyer flask. Using a 10 mL graduated cylinder, add 1.3 mL of deionized water to the flask and swirl the solution several times to mix (it is important to measure accurately and to swirl thoroughly in this step). Note the color in your notebook. If the solution is still blue, add a couple of more drops of water until the solution has a noticeable color change.
