You can use NaCl to season food for taste, and a little is needed as the body needs to maintain 0,9% salinity, not more nor less.

NaCl in excess is also poisonous so it is used to kill plants, get rid of animals and preserve food.

Many kinds of salt have industrial, agricultural and medical uses.

Salts also alter the boiling and freezing points of water.

KCl (nowadays replaced with NaCl) has been used to melt snow and ice on roads.

Sodium glutamate is used to enhance flavours in cooking.

Also bensoates and nitrates are used in food production.

Soil is fertilised with nitrates, phosphates and sulfates.

Plaster is made of calcium sulfate

Acetates are used for polymers.

In certain spritual beliefs salt is used to protect from evil spirits.
