salt vs ice experiment shorts

Salt lowers the freezing point of water to below zero degrees Celsius. When you add salt to the ice cube, it melts a thin layer on the ice cube. The water then refreezes around the string, allowing you to pick it up!
We sprinkle salt on the roads to keep ice from forming.What happens when salt reacts with ice?
When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on.
