Acid A substance which ionizes to form H+ (H+ is a product).ExamplesHNO3(aq) H+(aq) + NO3-(aq)HCl(aq) H+(aq) + Cl-(aq)
Base A substance that accepts (reacts with) H+.ExamplesOH-(aq) + H+(aq) H2O(l)NH3(aq) + H+(aq) NH4+(aq)Note that to obtain hydroxide ions (OH-) we start with an ionic compound that dissolves in water to form hydroxide ions, such as the alkali metal hydroxides, LiOH, NaOH, KOH, RbOH, etc.Since both acids and bases dissolve in water to form ions, they are both electrolytes. However, most acids and bases do not completely dissociate to form ions, those that do are called strong acids or strong bases.
Salt Any ionic compound whose anion comes from an acid and whose cation comes from a base.
