Bases are defined as electron pair donors . Neutralization reactions are accompanied by coordinate covalent bond formation. The Lewis Theory One Lewis acid-base example is the ionization of ammonia. The Lewis Theory Look at this reaction in more detail paying attention to the electrons. The Lewis Theory A second example is the ionization of HBr. HBr + H 2 O ® H 3 O + + Br - acid base The Lewis Theory Again, a more detailed examination keeping our focus on the electrons. The Lewis Theory A third Lewis example is the autoionization of water. You do it The Lewis Theory The reaction of sodium fluoride and boron trifluoride provides an example of a reaction that is only a Lewis acid-base reaction. It does not involve H + at all, thus it cannot be an Arrhenius nor a Brønsted-Lowry acid-base reaction. NaF

Unformatted text preview: + BF 3 ® Na + + BF 4-You must draw the detailed picture of this reaction to determine which is the acid and which is the base. The Lewis Theory The Lewis Theory BF 3 is a strong Lewis acid. Another example of it reacting with NH 3 is shown in this movie. Acid-Base Theories Look at the reaction of ammonia and hydrobromic acid. NH 3 + HBr ® NH 4 + + Br-Is this reaction an example of: 1. Arrhenius acid-base reaction, 2. Brønsted-Lowry acid base reaction, 3. Lewis acid-base reaction, 4. or a combination of these? You do it! It is a Lewis and Brønsted-Lowry acid base reaction but not Arrhenius. Acid-Base Theories Arrhenius, Brønsted-Lowry, and Lewis Acid-Base Theories expand on one another. 10 Reactions in Aqueous Solutions I: Acids, Bases & Salts...
