Chapter 19, Problem 9QAP

Interpretation Introduction

(a)

Interpretation:

The formula for the carbonate salt of $\left[\text{Co}{\left(en\right)}_2\left(\text{SCN}\right){\text{Cl}}^{+}\right]$ complex needs to be determined.

Concept introduction:

Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cationic or anionic. 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:

The formula for the barium salt of $\left[\text{Ni}{\left(\text{CN}\right)}_{\text{4}}{}^{2-}\right]$ complex needs to be determined.

(c)

Interpretation:
