# What are some examples of salt?

Dec 31, 2016

Any ionic solid will be a salt.

#### Explanation:

Another name for salt is ionic solid. These are compounds consisting of a positive ion (generally a metal) plus a negative ion, which can be a non-metal ion or a polyatomic ion, such as $N {O}_{3}^{-}$ or $S {O}_{4}^{2 -}$.

Salts exist in the form of crystalline solids showing a characteristic crystal pattern in the arrangement of the ions. Many are soluble in water, though many exceptions exist.

Examples of salts include

sodium chloride, $N a C l$
magnesium sulfate, $M g S {O}_{4}^{2 -}$
ammonium nitrate, $N {H}_{4} N {O}_{3}$
