What Is The Oxidation State Of Zn In Zn(NO2)2?

The oxidation state of Zn in Zn(NO2)2 is +2. The nitrite ion (NO2-) has an overall charge of -1, and since there are two NO2- ions present in the compound, the total charge contributed by them is -2. Since Zn(NO2)2 is a neutral compound, the sum of the oxidation states of all the atoms in it must be equal to zero. Therefore, the oxidation state of Zn must be +2 to balance out the -2 charge contributed by the NO2- ions.
