it makes the water a solution and therefore changing the properties of the frozen water first and foremost. However the most poignant idea that salt does to the frozen water is lower the freezing the point so, in effect, melts the ice. It also make the boiling point raise ever so slightly.

Salt or almost anything else dissolved in water elevates the boiling point and depresses the freezing point. If water ice is in contact with liquid water then almost any substance that dissolves in the water will make the adjoining ice melt (because it is no longer cold enough to freeze). Salt added to water will make it boil at a higher temperature, as well, but quite a bit (not just a pinch) is required.

Salt lowers the melting point of water making the ice melt easier.

Freezing point of salt water is lower than fresh water. The salt lowers the freezing point of the water/ice. As a result, the salt/water/ice combination gets much colder than 0°C (32°F), which is the freezing point of pure water. This pinciple is used in homemade ice cream machine.

Salt, or Sodium Chloride, NaCl, doesn't really "melt" ice...salt makes water more dense, which means it takes a longer time to freeze...Potassium Chloride melts ice....

salt absorbs water which increases ice's melting rate

it keeps it colder longer and speeds up the chilling process
