Chapter 21, Problem 21.142MP

Interpretation Introduction

(a)

Interpretation:

The equilibrium concentration of $A{u}^{3+}$ in a 0.050 M solution of ${[Au{(SCN)}_4]}^{-}$ is to be determined. Where, $K_f={10}^{37}$.

Concept introduction:

The formula that will be used −

$K_f=\frac{[Product]}{[Reactant\text{A}][Reactant\text{B}]}$

Interpretation Introduction

(b)

Interpretation:

The crystal field energy diagram and the number of unpaired electrons of the complex ${[Au{(SCN)}_4]}^{-}$ are to be determined.

Concept introduction:

The energy level diagram is used for the representation of energy shell, sub-shell, and orbital that is occupied by the electrons of the atoms.
