The unique property of iron that would be BEST to separate the iron filings from the salt is C. magnetism. Since iron is attracted to magnets, you could use a magnet to pull the iron filings away from the salt crystals, making magnetism the most effective method for separation.
Iron is the most common element forming the planet Earth and can be found in Earth's outer and inner core. It is the fourth most common element in the Earth's crust as well. Fresh iron surfaces appear silver-gray, but rusts easily in normal air. It is a solid at room temperature, but it is a soft metal. It is malleable and used for many tools and utensils. Iron is attracted to a magnet and can be magnetized. The melting point of iron is 2800oF.
