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. According to the Bible, Lot's wife was converted into a pillar of salt when she looked back at the destruction of Sodom.
Bonneville Salt Flats
30,000 acres of Utah that was part of an ancient lake basin named after explorer Captain B.L.E. Bonneville and his 1830 expeditions. 15,000 years ago it was an ancient lake the size of Lake Michigan. The salt surface contains potassium, magnesium lithium and sodium chloride (common table salt).  A place so flat you seem to see the curvature of the planet and so barren not even the simplest life forms can exist. Today, it is a world famous automobile race point. The world record land speed set there was Gary Gabolich's rocket car the "Blue Flame", attained 622.4 miles per hour in 1970.
