Chapter 19, Problem 8QAP

Interpretation Introduction

(a)

Interpretation:

To determine the oxidation number of the metal atom in ${\left[\text{Fe}{\left({\text{H}}_{\text{2}}\text{O}\right)}_{\text{6}}\right]}^{3+}$.

Concept introduction:

Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.

The total charge present on any complex ion is equal to the sum of the oxidation number of the central metal atom and the total charges of the ligand present in it.

Interpretation Introduction

(b)

Interpretation:

To determine the oxidation number of the metal atom in ${\left[\text{Pt }\left({\text{NH}}_{\text{3}}\right){\text{Br}}_3\right]}^{-}$.

Concept introduction:

Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.

The total charge present on any complex ion is equal to the sum of the oxidation number of the central metal atom and the total charges of the ligand present in it.

Interpretation Introduction

(c)

Interpretation:

To determine the oxidation number of the metal atom in ${\left[\text{V}\left(\text{en}\right){\text{Cl}}_{\text{4}}\right]}^{2-}$.

Concept introduction:

Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.

Interpretation Introduction

(d)

Interpretation:

To determine the oxidation number of the metal atom in ${\left[\text{Au}{\left(\text{CN}\right)}_{\text{2}}\right]}^{+}$.

Concept introduction:
