Study Notes
Complexometric Titration
- The anion or neutral molecule involved in complexometric titration is called a complexing agent.
Central Metal Requirements
- Central metals must have free coordination sites in order to participate in complexometric titration.
Coordination Bonds
- The number of coordination bonds around the central metal in a coordination compound is determined by the valence shell electron pair repulsion (VSEPR) theory.
Ligand Classification
- Ligands are classified as monodentate, bidentate, or polydentate based on the number of sites attached to the metal ion.
Coordination Bonds Formation
- The combination of a metal ion as an acceptor with a ligand through coordinated bonds is called coordination.
