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. Brnsted-Lowry acid base reaction, 3. Lewis acid-base reaction, 4. or a combination of these? You do it! It is a Lewis and Brnsted-Lowry acid base reaction but not Arrhenius. Acid-Base Theories Arrhenius, Brnsted-Lowry, and Lewis Acid-Base Theories expand on one another. 10 Reactions in Aqueous Solutions I: Acids, Bases & Salts...
