Question
### Matching Aqueous Solutions with Boiling Points In this exercise, you are to match the following aqueous solutions with the appropriate boiling point category listed in the column on the right. 1. 6.6×10⁻² m \( \text{Al}_2(\text{SO}_4)_3 \) 2. 9.0×10⁻² m \( \text{AlI}_3 \) 3. 0.21 m \( \text{CoSO}_4 \) 4. 0.39 m Glucose (nonelectrolyte) #### Categories for Boiling Points A. Highest boiling point B. Second highest boiling point C. Third highest boiling point D. Lowest boiling point To solve, you must consider the colligative properties of solutions. Colligative properties depend on the number of particles in a solution. Ionically dissociating compounds increase the number of particles in solution. ### Analysis - **\( \text{Al}_2(\text{SO}_4)_3 \)**: Dissociates into 2 \( \text{Al}^{3+} \) and 3 \( \text{SO}_4^{2-} \); total of 5 particles. - **\( \text{AlI}_3 \)**: Dissociates into 1 \( \text{Al}^{3+} \) and 3 \( \text{I}^{-} \); total of 4 particles. - **\( \text{CoSO}_4 \)**: Dissociates into 1 \( \text{Co}^{2+} \) and 1 \( \text{SO}_4^{2-} \); total of 2 particles. - **Glucose**: Does not dissociate; 1 particle in solution. ### Conclusion Knowing the number of dissociated particles: - \( \text{Al}_2(\text{SO}_4)_3 \) will have the highest boiling point. - \( \text{AlI}_3 \) will have the second highest boiling point. - \( \text{CoSO}_4 \) will have the third highest boiling point. - Glucose, as a nonelectrolyte and with no dissociation, will have the lowest boiling point. Thus, the solutions match with: 1 → A 2 → B 3 → C 4 → D
