Mr. Anderson explains acid-base equilibrium, focusing on the reversible nature of reactions and the role of equilibrium constants. He discusses the importance of water in these reactions, highlighting its amphoteric properties. The video covers the difference between strong and weak acids/bases, using equilibrium constants to determine their strength. Neutralization reactions and titration curves are also explained, illustrating how pH changes during these processes. The video aims to clarify these concepts, making them more accessible to students.
