Chapter 3, Problem 72P

Interpretation Introduction

Interpretation:

The oxidation numbers to each atom in the following species should be assigned.

  ${\text{NH}}_{\text{4}}{\text{NO}}_{\text{3}}$ , ${\text{CaMgSiO}}_4$ , ${\text{Fe(CN)}}_6^{4-}$ , ${\text{B}}_{\text{2}}{\text{H}}_{\text{6}}$ , ${\text{BaH}}_{\text{2}}$ , ${\text{PbCl}}_2$ , ${\text{Cu}}_{\text{2}}{\text{O(SO}}_{\text{4}}\text{)}$ , ${\text{S}}_4{\text{O}}_6^{2-}$

Concept Introduction:

Oxidation state is also known as oxidation number. It is defined as the numbers which are assign to the elements in a chemical combination and number represents the electrons which an atom can share, lose or gain to form chemical bonding with an atom of another element.

Therefore, transfer of electrons refers to the oxidation state.
