This lecture provides a comprehensive academic overview of complex formation titrations, with a primary focus on EDTA complexometric titration, a widely used method in quantitative analysis of metal ions.

📘 Lecture Objectives:
• Define and explain the principles of complexometric titration
• Understand the role of chelating agents, particularly ethylenediaminetetraacetic acid (EDTA)
• Discuss metal-ligand complex stability.
• Explore the stoichiometry of complex formation reactions.

🔬 This lecture is suitable for:
• Undergraduate students in pharmaceutical sciences, chemistry, and environmental science
• Learners preparing for practical or theoretical examinations in analytical chemistry
• Anyone seeking a deeper understanding of quantitative metal ion analysis
