3.1uuBehavior of many acids and bases can be explained by the Arrhenius theory. Arrhenius acids and bases are electrolytes.
3.1vvArrhenius acids yield H+(aq), hydrogen ion as the only positive ion in an aqueous solution. The hydrogen ion may also be written as H3O+(aq), hydronium ion.
3.1ww Arrhenius bases yield OH-(aq), hydroxide ion as the only negative ion in an aqueous solution.
3.1xx In the process of neutralization, an Arrhenius acid and an Arrhenius base react to form a salt and water.
3.1yy There are alternate acid-base theories. One theory states that an acid is an H+ donor and a base is an H+ acceptor.
3.1zz Titration is a laboratory process in which a volume of a solution of known concentration is used to determine the concentration of another solution.
