3.2.2.2 experiments.• Bring all test tubes to warm up in hot water 50 – 60° c for 10 minutes.So that all substances melt• Insert the magnetic stirring rods the substance. Close the lid, and then cover with paper tubes and hot froi.Percussion (Stirrer) with a temperature of 100° c, leave it for 6 hours.• To observe and record the results.• Bring in test tubes to filter in the filtration additives. After you finish using the eyedropper filtered substances dripChase pending metabolites of alcohol in test tubes on the filter paper filter paper to dry until.• Remove the suction device inserted in the filter paper moisture (desiccator) and leave to absorb moisture.• Paper filter to observe the color of the Cu.3.2.2 control creation series of experiments to compare the results from trials 1 by throttling.CuCl2 and volume of slurry, which can be split into 2 sets of experiments, as follows:3.2.2.1 preparation• Weighing chemicals put into test tubes, respectively.
