In chemistry, a Salt is just a molecule with a positive ion and a negative ion that results in a molecule with no charge. We call NaCl (sodium chloride) “salt” or “table salt” but really it’s just one kind of salt.

CaCl is also a salt, but it has a calcium ion instead of a sodium ion.

Salts tend to break into their ions in water, and might make the water more acidic or basic. Often, the additional ions will lower the freezing temperature. That’s why calcium chloride is popular for road salt.
