Question

Calcium chloride is added to the roadways after a snowstorm. Which colligative property is being showcased here?

A) osmotic pressure

B) boiling point elevation

C) vapor pressure lowering

D) freezing point depression

Answer 1

Option (D) freezing point depression

Step-by-step explanation:

Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.
