Why does an electrolyte depress the freezing point of a solvent more than a nonelectrolyte?
a) Electrolytes increase pressure.
b) Electrolytes dissociate into ions.
c) Electrolytes have higher molecular weights.
d) Electrolytes lower vapor pressure.

Explanation:

b) Electrolytes dissociate into ions.

Answer: B

Explanation:

The freezing point depression induced by an electrolyte is greater than that of a non-electrolyte when they have the same molality (moles of solute per kilogram of solvent). This difference arises because electrolytes, when dissolved in water, undergo ionization, leading to the formation of more ions in the solution. As a result, electrolytes contribute a higher number of solute particles, amplifying their impact on freezing point depression.
