| Salt lowers the freezing temperature of water. So putting salt on snow makes it melt. Its for getting rid of slippery ice on sidewalks and roads.

| Most generally they put it on ice on roads, and the reason they do it is that ice water has a lower freezing point than fresh water. The salt converts the ice to salt water and it melts.The salt also offers a little bit of a traction factor acting a little like gravel, but the main effect is the melting.There are other less caustic chemicals that help melt ice, and these are used as well.
