Lecture
This lecture introduces the fundamentals of acids and bases, covering topics such as acid-base reactions, proton donors and acceptors, acid strength, equilibrium constants, and the relationship between acid-base pairs. The lecture also explores the concept of amphoteric substances and provides examples of different types of acids and bases. The instructor discusses the autoprotolysis of water, constant acidity and basicity, and the significance of equilibrium constants in acid-base reactions.
