Q
Q: Which of the following solutions will have the highest boiling point?
Solution:
0.1 M MgCl2 will have the highest boiling point due to the highest van 't Hoff factor (i = 3).
Steps: 5
Show Steps
Step 1: Understand that boiling point elevation depends on the number of particles in solution.
Step 2: Identify the van 't Hoff factor (i) for each solute. This factor tells us how many particles each solute breaks into when dissolved.
Step 3: For MgCl2, it dissociates into 3 particles: 1 Mg^2+ ion and 2 Cl^- ions. So, i = 3.
Step 4: Compare the van 't Hoff factors of other solutions (if provided) to see which has the highest value.
Step 5: The solution with the highest van 't Hoff factor will have the highest boiling point.
