Question 2
Solubility and SolutionsIn countries where the temperature falls below 273K, salt is always sprinkled on the icy roads in order to
- A.lower the melting point of the ice
- B.increase the density of the ice
- C.make the ice impure
- D.raise the melting point of the ice.
Show the answer and explanation
Answer: A (lower the melting point of the ice)
Explanation
Dissolved salt lowers the freezing (melting) point of water, so the ice melts even below 0°C (273 K).
