Salts are compounds that contain positively charged ions and negatively charged ions. That is; they consist of the positive ion of a base and the negative ion of an acid.
Salts may be produced when acids and bases are combined together in equal proportions, a process called neutralization.
During neutralization reactions an acid reacts with a base to form a salt and water as the only products.
Because the oily part of its molecule tends to lay up against solid surfaces, but without much in the way of areas of electric charge that would cause it to stick more firmly to that surface.
