Question

what is the oxidation number of Zn(NO3)2​

Answer 1

in Zn(NO3) 2 , the oxidation number of only Zn is +2.

and the oxidation number of (NO3) is -1 .

so the oxidation numer of Zn (NO3)2 = 0.

Answer 2

Given:

Given compound is $Zn(NO_3)_2$.

To find:

The oxidation number of Zn.

Solution:

The compound is $Zn(NO_3)_2$.

We know that the oxidation state of $NO_3$ is -1.

Again this compound contains two $NO_3$ groups.

Let the oxidation number of Zn be x.

The overall charge of the compound is 0.

So, we can write-

$x + ( - 1) \times 2 = 0 \\ x = + 2$

The value of x is +2.

So, the oxidation state or number of Zn in zinc nitrate is +2.
