Acid-Base Titrations

This lecture covers the definitions and methods of volumetric titrations, focusing on acid-base titrations. It explains how titrations determine the amount of acid or base in a solution by reacting it with a strong base or acid. The lecture also discusses the use of strong acids and bases as standard solutions, the concept of equivalence point, and the role of indicators in detecting the endpoint of a titration. Additionally, it explores the use of mixed indicators to narrow down the color change range and the distribution diagrams for acid-base titrations of weak acids. The lecture concludes with examples of titrating weak acids and bases, such as phosphoric acid and carbonate, and the calculation of pH at different points of the titration.
