Question

What happens when one freezes salt water?

A - The solvent particles make it easier for the water molecules to form crystals.
B - The solute particles make it harder for the water molecules to form crystals.
C - The solvent particles make it harder for the water molecules to form crystals.
D - The solute particles make it easier for the water molecules to form crystals.

Answer 1

The answer is B.

The solvent is the part of solution in which the solute is dissolved. Salt, being the solute, makes it harder for water to crystallize into a formal lattice, requiring a lower temperature to trigger the freezing into an irregular structure.
