Answer Details
Salt is sprinkled on icy roads in cold countries to lower the melting point of the ice. When salt is spread on the ice, it dissolves and creates a brine solution with a lower freezing point than pure water. This means that the ice will start to melt even when the temperature is below its normal freezing point, making the road safer for vehicles and pedestrians to use. In other words, the salt helps prevent the road from becoming too slippery and dangerous by melting the ice at lower temperatures.
