Challenge Problems

Push your limits with challenges.

Question 1

Using both Brønsted-Lowry and Lewis theories, analyze the reaction between acetic acid (CH₃COOH) and sodium hydroxide (NaOH). Identify the acids, bases, conjugates, and how they fit into both theories.

💡 Hint: Identify proton donors and acceptors in the reaction for each theory.

Question 2

Evaluate the statement: 'All reactions between Lewis acids and bases must involve protons.' Discuss and provide an example to support your argument.

💡 Hint: Focus on the distinctions between Lewis and Brønsted-Lowry definitions.
