Question

why do we put salt on side walls when it snows?

Answer 1

✨✨Answer✨✨

➡️✨✨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✨✨

Answer 2

Hey mate here is your answer ⬇️

Salt is added on walls when it snows because 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.
