    While there are plenty of clever uses for salt, including fixing slippery surfaces, rock salt isn’t always easy to find once temperatures drop lower than the melting point of ice (32°F or 0°C).

    en.wikipedia.org/wiki/Halite

    Halite is also often used both residentially and municipally for managing ice. Because brine (a solution of water and salt) has a lower freezing point than pure water, putting salt or saltwater on ice that is below 0 °C (32 °F) will cause it to melt—this effect is called freezing-point depression.

    en.wikipedia.org/wiki/Water_softening

    Water containing these minerals is known as "hard water". [citation needed] When hard water is heated in a plumbing system, carbon dioxide goes out of solution, and bicarbonates become carbonates, which are much less soluble. The carbonates bind to plumbing surfaces providing seed crystals for further crystal growth, which build up as hard scale.

Anti-icing is the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.

    en.wikipedia.org/wiki/Snow_removal

    The salt, via freezing point depression, helps melt the snow and ice and also gives vehicles more traction. Later, usually when the snow has ceased falling, snow plows, front end loaders with snowplow attachments, and graders cover every street pushing snow to the side of the road. Salt trucks often then return to deal with any remaining ice ...
