Chapter 21, Problem 21.105SP

Interpretation Introduction

Interpretation:

The difference of colors exhibited between ${\left[{\text{Cr(H}}_2{\text{O)}}_{\text{6}}\right]}^{\text{3+}}$ and ${\left[{\text{Cr(CN)}}_{\text{6}}\right]}^{\text{3-}}$ needs to be explained using crystal field theory. The order of H₂O and CN- in spectrochemical series needs to be determined.

Concept introduction:

Spectrochemical series is list of ligands arranged based on its strength and list of metal ions based on oxidation number of metals.
