Acids and Bases Concepts

Teacher Adam introduces the topic of acids, bases, and salts, explaining their definitions and examples. The video covers the concept of proton donors and acceptors, and discusses the strengths of acids and bases. It also distinguishes between dilute and concentrated acids. The session concludes with a preview of the next class.
