This episode is about acid-base equilibrium. It defines acids and bases according to Arrhenius and Bronsted-Lowry, emphasizing the concepts of conjugate acid-base pairs and the importance of understanding ionization. It goes on to explain the relationship between acid strength and ionization, highlighting the difference between strong and weak acids and bases. It then delves into the calculation of pH for weak acids and bases using the Ka and Kb constants, and finally explores the impact of salts on pH through hydrolysis. The episode concludes with a cheat sheet summarizing the key concepts and relationships related to acid-base equilibrium.
