Question

5. If you had 0.10 m solutions of each of the solutions in question #4, which would have: (hint, more ions cause bigger colligative properties, few particles in solution | K" ("C/m) Pure Solvents Water Ethanol Benzene | Ke rc/m ) 0.512 1.19 2.65 1.86 1.99 -5.12 will have a smaller colligative affect.) d. the highest vapor pressure? e. the lowest freezing point? a. the highest boiling point? b. the highest freezing point? c. the lowest osmotic pressure? 6. Calculate the boiling point elevation and the freezing point depression AND the actual boiling and freezing points for: (data to the right) Boiling Point 100.0 78.5 80.1 Freezing 0.0 114.1 5.5 Pure Solvents Point Water Ethanol Benzene a. 1.50 m potassium carbonate in water b. 1.50m methanol (CH-OH) in water (hint, do covalent compounds ionize?) c. 1.50 m wax dissolved in benzene solvent (wax will not ionize) d. 5.53 m acetone dissolved in ethanol (no ionization)
