In chemistry, a salt is an ionic compound composed of cations and anions forming a neutral product and without net charge. These ions can be as well inorganic (Cl- chloride) as organic (CH3COO- acetate) and monoatomic (F- fluoride) as well as polyatomic (SO4 (2-) sulfate).
Salt solutions in water are called electrolytes because they conduct electricity.
Molten salts are just as conductive as electrolytes.
Commensalism is an association between two different species where one species enjoys a benefit and the other is not significantly affected. Probably the best example of commensalism is the relationship between cattle egrets and large herbivores
