Which of the following will have the lowest freezing point?

Which of the following will have the lowest freezing point?

Step 1: Understand that freezing point depression occurs when a solute is added to a solvent, lowering the freezing point.
Step 2: Know that the freezing point depression depends on the number of particles the solute breaks into when dissolved.
Step 3: Identify the solute in the question. In this case, we have 0.1 m MgCl2.
Step 4: Determine how many particles MgCl2 produces when it dissolves in water. It breaks into 1 magnesium ion (Mg2+) and 2 chloride ions (Cl-).
Step 5: Count the total number of particles produced by 0.1 m MgCl2: 1 (Mg2+) + 2 (Cl-) = 3 particles.
Step 6: Compare this with other options (if provided) to see which produces the most particles.
Step 7: Conclude that since 0.1 m MgCl2 produces the most particles, it will have the lowest freezing point.
