Question 1.
Define colligative properties.
Show hintHide hint
Think about how the amount of solute affects solution characteristics.
Question 2.
What happens to a solvent's vapor pressure when a solute is added?
Show hintHide hint
Consider the escape of solvent molecules.
3Question 3.
What is the formula for boiling point elevation?
- \$\\Delta T_b = K_b \\cdot m\$
- \$P = CRT\$
- \$\\Delta T_f = K_f \\cdot m\$
Show hintHide hint
Look for the formula that mentions boiling point.
4Question 4.
True or False: Colligative properties depend on the chemical nature of the solute.
- True
- False
Show hintHide hint
Consider the definition of colligative properties.
Question 5.
If 2 moles of NaCl are dissolved in 1 kg of water, what will be the boiling point elevation? Use $K_b = 0.52° C/m$ . Assume NaCl dissociates completely to 2 particles.
Show hintHide hint
Remember to factor in the dissociation of NaCl.
Question 6.
A solution is prepared by dissolving 1 mol of glucose (C6H12O6) in 1 kg of water. Calculate the freezing point depression if $K_f = 1.86° C/m$ .
Show hintHide hint
Consider that glucose simply adds to molality.
