Chapter 22, Problem 68E

Interpretation Introduction

Interpretation:

The reduction potential for the reduction of ${\text{NO3}}^{\text{-}}$ to ${\text{NO2}}^{\text{-}}$ in a basic solution should be determined.

Concept introduction:

Group-15 elements have ${\text{ns}}^{\text{2}}{\text{, np}}^{\text{3}}$ valence shell configuration. They have tendency to show many oxidations states from +5 to -3. This is why a wide range of compounds like oxides, halides, and hydride are known for the elements of group-15. Nitrogen is the first element of this group and due to small size, high electronegativity and tendency to form hydrogen bonding it exhibits anomalous behavior
