Which of the following solutions will have the lowest freezing point? A)0.010 mol kg^-1 KBr B)0.010 mol kg^-1 Na₂CO₃ C)0.035 mol kg^-1 CH₃CH₂OH D)0.015 mol kg^-1 BaCl₂

Question

Quizplus · Accepted Answer

The solution with the lowest freezing point is the one with the highest molality and the greatest number of particles produced when dissolved. BaCl2 dissociates into 3 ions (1 Ba2+ and 2 Cl-), and with a molality of 0.015 mol/kg, it will produce more particles in solution compared to the other options, thus lowering the freezing point the most.
