Anti-icing agents are substances used to prevent the formation of ice on surfaces, especially in cold weather. These agents work by lowering the freezing point of water, making it harder for ice to form. Commonly used in road maintenance, they help keep highways and sidewalks safe during winter storms by reducing slippery conditions. One popular type of anti-icing agent is salt, which is often mixed with water to create a brine solution. Other alternatives include calcium chloride and magnesium chloride, which are effective at lower temperatures. By applying these agents before a snowstorm, cities can minimize ice buildup and improve safety for drivers and pedestrians.
