Expert Answer

Step 1

Oxidation is the process that involved the loss of electrons and oxidized to cation whereas reduction is the process that involved the gain of electrons and reduced to anion.

Step 2

The term oxidation number indicates the charge on atom after losing or gaining electron and form ion.

Step 3

In O22−;

Let’s assume the oxidation number...

2 x -2
x -1
