Which of the following will have the lowest freezing point? A) 0.1 M NaCl B) 0.1 M BaCl₂ C) 0.1 M AlCl₃ D) All have the same freezing point.

Question

Quizplus · Accepted Answer

The freezing point depression is directly proportional to the number of ions in solution. AlCl₃ dissociates into four ions (Al³⁺ and 3 Cl⁻), which is more than NaCl (2 ions) and BaCl₂ (3 ions), resulting in the lowest freezing point.
