Q
Q: Which of the following solutions has the highest boiling point?
Solution:
CaCl2 dissociates into 3 ions (Ca^2+ and 2 Cl^-), leading to the highest boiling point elevation among the options.
Steps: 6
Show Steps
Step 1: Understand that boiling point elevation occurs when a solute is added to a solvent.
Step 2: Know that different solutes can dissociate into different numbers of ions in solution.
Step 3: Identify the solute in the question (CaCl2) and determine how many ions it produces when it dissolves.
Step 4: Recognize that CaCl2 dissociates into 3 ions: 1 calcium ion (Ca^2+) and 2 chloride ions (Cl^-).
Step 5: Compare this with other solutes (if provided) to see how many ions they produce.
Step 6: Conclude that the more ions produced, the higher the boiling point elevation, making CaCl2 the solution with the highest boiling point.
