Here are at least three uses of salt:

1. Food Preservation: Salt is used to preserve food by drawing out moisture through osmosis, which inhibits the growth of bacteria and fungi. This method is commonly applied to meats, fish, and vegetables.
2. Flavoring: Salt is a fundamental seasoning that enhances the taste of food, balancing and intensifying other flavors in dishes.
3. De-icing Roads: In colder climates, salt (sodium chloride) is spread on roads and sidewalks to lower the freezing point of water, preventing ice formation and melting existing ice, thus improving safety.
