CHM 109 General Chemistry ! Experiment 11: Investigation of Intermolecular Forces and Solubility 2. The interaction between a Cu2+ ion and several water molecules will look exactly like Figure 4. Using this idea, explain your observations of the solubility of Cu2in ethanol. 3 Describe the IMF interactions between water and ethanol molecules, as well as those Either describe the interactions in words, and/or provide an annotated sketch between water and hexane molecules. Use this information to explain the your observations of their miscibility. 4. lodine, (12), can be electrochemically reduced to form the triiodide ion, (13). Predict the solubility, or lack thereof, of is in water and hexane. Why might its solubility differ from that of 12
