Bronsted-Lowry Acid-Base Concepts

In this video, Chris Harris from ourretreaters.com explains the concept of conjugate acids and bases. The video covers the definitions of acids and bases, the concept of conjugate pairs, and how these pairs are involved in equilibrium reactions. It includes a generic equation example and a specific example using hydrofluoric acid to illustrate the formation of conjugate pairs. Additionally, the video discusses a base example and a nitration reaction to show how substances can act as acids or bases depending on the reaction context.
