Question: Which of the following solutions would have the highest boiling point?

Options:

Correct Answer: 0.1 m CaCl2

Solution:

0.1 m CaCl2 produces three particles (Ca2+ and 2 Cl-), leading to the highest boiling point elevation among the options.

Which of the following solutions would have the highest boiling point?

Which of the following solutions would have the highest boiling point?

Step 1: Understand that boiling point elevation depends on the number of particles a solute produces in solution.
Step 2: Identify the solute in the options provided. In this case, we have CaCl2.
Step 3: Determine how many particles CaCl2 produces when it dissolves in water. It breaks into one calcium ion (Ca2+) and two chloride ions (Cl-).
Step 4: Count the total number of particles produced by 0.1 m CaCl2: 1 (Ca2+) + 2 (Cl-) = 3 particles.
Step 5: Compare this with other options (if provided) to see how many particles they produce.
Step 6: Conclude that since 0.1 m CaCl2 produces the most particles, it will have the highest boiling point elevation.
