HC H acetone 1. a) What would you expect the magnitude and sign of AHSOLUTE, AHSOLVENT, and AHMIXING to be for CH2Cl2 as solute and acetone as solvent? Circle your ci H choices below. Then, fill in the most important IM force that exists between solute CH.CI, molecules, between solvent molecules and between solute and solvent molecules. solute solvent Magnitude Sign Most important force between: AHSOLUTE small moderate large Positive Negative solute and solute AHSOLVENT small moderate large Positive Negative solvent and solvent_ AHMIXING small moderate large Positive Negative solute and solvent_ b) Based on this, what is the overall enthalpy change (AHSOLUTION) for dissolving CH2Cl2 in acetone expected to be? (negative/positive/near zero). Would you expect CH2Cl2 to dissolve in acetone? (yes/no). Explain your answers to both of the questions above. Consider the energy and entropy contributions discussed in class. нно 2. Consider the two molecules shown here. The solubilities of each in water is given. Η Η Η Η
