Q. In many countries with cold climates, the municipalities often sprinkle salt on icy roads in winter. 
Which among the following is the correct reason for this?
Answer: The Salt lowers the Freezing Point of water
Notes: The correct reason for sprinkling salt on icy roads is that "the salt lowers the freezing point of water." This process is known as freezing point depression. When salt (sodium chloride) is added to ice, it disrupts the formation of ice crystals, causing the ice to melt at lower temperatures. This is why salt is commonly used in winter road maintenance. it helps to keep roads safer by preventing ice formation. In fact, salt can lower the freezing point of water to about -9.5°C (15°F) when used in sufficient quantities.
