Bronsted-Lowry Acid-Base Concepts

The video tutorial introduces the Bronsted-Lowry theory of acids and bases, explaining that acids are proton donors and bases are proton acceptors. It uses the reaction between ammonia and water to illustrate these concepts, showing how ammonia acts as a base by accepting a proton from water, which acts as an acid. The tutorial also covers the concept of conjugate acid-base pairs, explaining how the acid becomes a conjugate base after donating a proton, and the base becomes a conjugate acid after accepting a proton.
