Imagine the ice molecules are like Lego bricks tightly stacked together. When you add salt, it’s like inserting a layer of very small slippery marbles between the Lego bricks. This makes it harder for the bricks to stick together, and they start to loosen up and slide around, causing the ice to melt.
That’s why we use salt on icy roads and sidewalks during winter, it helps melt the ice, making it safer to walk and drive on.
