  1. 0.1 m NaCl
  2. 0.1 m KCl
  3. 0.1 m CaCl2
  4. 0.1 m glucose

Questions & Step-by-Step Solutions

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.
