"We believe this is a huge salt deposit," Dawn's principal investigator Chris Russell told a crowd of scientists Monday at the European Planetary Science Congress in Nantes, France, in a talk that was posted online Thursday. "We know it's not ice and we're pretty sure it's salt, but we don't know exactly what salt at the present time. "

Salts are formed by the combination of an acid and a base. There are various varieties of salt. Many of which you would not want to sprinkle on your tomato.

Salts are formed by the combination of an acid and a base.
The presence of salt’s other dominant ion, chloride, results from outgassing of chloride (as hydrochloric acid) with other gases from Earth's interior via volcanos and hydrothermal vents.
Instead of thinking of salt as a specific type of mineral, think of it as something originating from an evaporated solution of various metal and halogen ions.
In chemistry, a salt is an ionic compound that results from the neutralization reaction of an acid and a base.
