Submit Answer

Certain nitrites can be prepared by the chemical reduction of nitrates

2NO₃^-

2NO₂^-

CO₂

Assign an oxidation number to each atom and verify that the total number of electrons lost is equal to the total number gained.

Enter the oxidation numbers under each substance in the box corresponding to the element label to the left.

If a box is not needed, leave it blank.
