Concepts in Inorganic Chemistry - Lecture 9 | Concepts of Acids & Bases + HSAB Theory Explained

Описание: Welcome to Concepts in Inorganic Chemistry I | Lecture 9: Acids, Bases & HSAB Theory ⚛️

In this lecture, we explore the major theories of acids and bases, from classical definitions to modern concepts. We also introduce Pearson’s Hard and Soft Acids and Bases (HSAB) Principle, which helps explain stability, reactivity, and ligand preferences in inorganic chemistry.

🎯 Topics Covered:
• Arrhenius concept of acids and bases
• Brønsted–Lowry proton donor–acceptor theory
• Lewis acids and bases (electron pair theory)
• Pearson’s HSAB Principle – hard acids, soft acids, hard bases, soft bases
• Classification of acids and bases (hard, soft & borderline)
• Trends in metal ion–ligand stability
• Applications of HSAB theory:
– Stability of complexes
– Hard–hard vs soft–soft combinations
– Mixed ligand effects (Jorgensen’s rule)
– Symbiosis (ligand preference)
• Limitations of HSAB theory with examples

💡 Why Watch:
This lecture builds a strong conceptual foundation for understanding acid–base behavior, reactivity trends, and metal–ligand interactions. Ideal for university chemistry students, A/L students, and anyone studying inorganic chemistry.
