1. Theories of Acid & Bases and its limitations

Students should enlist various theories of acids and bases. Explain the differences between the Arrhenius, Bronsted-Lowry, and Lewis theories of acids and bases. Students should provide specific examples for each theory and illustrate how each theory explains the behavior of acids and bases. Students should discuss the limitations of each theory in explaining acid-base behavior.
