A salt is a compound consisting of a metal and a non metal that are bound by ionic bonds. They can be the resultant product of a conjugate acid and conjugate base in an acid-base reaction. Salts have an overall neutral charge. Most salts are made by reacting an acid and a base.
In common usage, salt often refers to sodium chloride (NaCl), known as table salt. Salt is used as a seasoning and a preservative. It can be formed by the reaction of sodium hydroxide (NaOH) and hydrochloric acid (HCl).
Salt is found naturally in salt water, like seas and oceans.
Salt is also used as a de-icing agent for roads and walkways during the winter months.
