Chapter 16, Problem 55E

Interpretation Introduction

Interpretation:

The oxidation state of every elements is to be determined for each of the given compound.

Concept introduction:

Oxygen acceptor tendency of any atom is oxidation state of that atom.

Oxidation state is defined as a charge which an atom of the element has in its ion or appears to have when present in the combined state with other atoms.

Rule for calculation of oxidation state is as follows:

In free element oxidation state of atom is $0$.

In monoatomic ion oxidation is equal to its charge.

The sum of oxidation of all atoms in neutral molecule is $0$.

In ionic compound oxidation state is equal to the charge on the compound.

Charge of oxygen is $-2$.

The oxidation of non-metals is calculated with the help of hierarchical table.

The charge on alkali metal is $+1$ and on alkaline earth metal is $+2$.
