Chemistry question about solutions

Why do we use salt on ice in cold weather?

  1. The combination increases the boiling point of the ice, making it melt faster.
  2. The combination increases the vapor pressure of the ice, so it evaporates faster.
  3. The combination makes salt water, which has a lower melting point than ice, so the ice melts.
  4. The combination increases the osmotic pressure of the ice, so it melts faster.
  5. The combination generates energy as the salt dissolves, which melts the ice.
