Acids and Bases: Equilibria and Solutions

This lecture covers the concepts of acids and bases, including the pH scale, chemical equilibria, buffer solutions, and quantitative processing. It explains the definitions of Brønsted-Lowry and Lewis acids and bases, as well as the equilibrium constants and activity in aqueous solutions. The lecture also delves into the autoprotolysis of water, acid-base conjugate couples, and the relative strengths of conjugate acid-base pairs. It discusses the pH of strong and weak acid solutions, as well as the pH of salts in water. Additionally, it explores the impact of salts on solution pH and the calculation of pH for various scenarios involving weak acids and bases.
