1. Which solvent, water or carbon tetrachloride, would BEST dissolve each
of the following? Why?
a. KrF2 H2O polar solute dissolves in polar solvent
b. SF2 H2O polar solute dissolves in polar solvent
c. SO2 H2O polar solute dissolves in polar solvent
d. CO2 CCl4 nonpolar solute dissolves in nonpolar solvent
e. MgF2 H2O ionic solute dissolves in polar solvent (actually insoluble, b/c Mg-F
attraction is much greater than h-bonds due to extremely high ΔEN)
f. CH2O H2O polar solute dissolves in polar solvent
g. CH2=CH2 CCl4 nonpolar solute dissolves in nonpolar solvent
2. Which solvent, water or hexane (C6H14), would you choose to dissolve each of the
following? Why?
a. NaCl, H2O; ionic solute dissolves in polar solvent
b. C6H12O6, H2O; polar solute dissolves in polar solvent
d. Octane (C8H18), hexane; nonpolar solute dissolves in nonpolar solvent
d. (NH4)2SO4, H2O; ionic solute dissolves in polar solvent
