Questions & Answers

Q: Why are transition metals preferred in forming complex ions?

Transition metals are preferred due to their variable oxidation states, which allow the formation of stable complex ions surrounded by ligands through the use of unpaired electrons.

Q: How does the charge radius ratio of transition metals influence complex ion formation?

Transition metals have a higher charge radius ratio, making them suitable for forming complex ions as they fulfill the criteria required for stable complex formation.

Q: How does the dissociation of complex ions differ based on the ligands surrounding the central metal ion?

Complex ions surrounded by strong-field ligands like cyanide have less dissociation in solution compared to ones with weak field ligands due to the strength of bonding.

Q: How does the algebraic sum of charges affect the net charge of a complex ion?

The net charge of a complex ion is determined by the algebraic sum of the charges of the constituent ions, such as the central metal ion and the ligands, resulting in a stable charge for the complex.

Summary & Key Takeaways

• Transition metals, like iron and cobalt, with variable oxidation states are central in forming stable complex ions surrounded by ligands.

• The charge radius ratio of transition metals is higher, contributing to their ability to form complex ions.

• The strength of the bond between the central metal and ligands determines the degree of dissociation in solution.
