Chapter 20, Problem 20.50SP

Interpretation Introduction

Interpretation:

The stronger oxidizing agent from given set of metal ions namely $C{r}^{2+}$ and ${\text{Cu}}^{\text{2+}}$ should be identified.

Concept Introduction:

Oxidation: If electrons are moved from a species during a chemical reaction. The species whose electrons are removed is said to be oxidized.

Oxidizing agent: The substances that are capable to oxidize other species by accepting electrons from those species are called oxidizing agent which gets reduced during the process.

Effective nuclear charge: It is the charge experienced by the valence electrons from the nucleus. Effective nuclear charge increases across a period because increasing nuclear charge with no accompanying increase in shielding effect.
