Lecture
This lecture covers the concepts of acids and bases, pH scale, acid dissociation constant, and buffer solutions. It explains how the concentration of H+ ions determines the acidity of a solution, the logarithmic scale of pH, and the relationship between pH and pOH. It also discusses the dissociation of weak acids and bases, the concept of buffer solutions, and the role of conjugate acid-base pairs. The lecture emphasizes the importance of identifying conjugate acid-base pairs, writing acid-base reactions, and calculating pH in different scenarios.
