Question

what is oxidation number of oxygen in hydrogen peroxide​

Answer 1

Answer:

The Oxidation number of O2 in Hydrogen peroxide is (-1)

Explanation:

We know that the common Oxidation state of oxygen is (-2). But, in peroxide bonds the oxygen atoms combine with each other resulting in oxidation of both the atoms and thus, increasing each others oxidation state by (1) i.e. upto (-1).

By formula:-

Oxidation state of Hydrogen:- (1)

[Since, When Hydrogen gets attached with a non metal it's oxidation state is taken as (+1)]

Oxidation state of Oxygen:- x

Then,

2(1) + 2x = 0

2 + 2x = 0

2x = -2

x = -1
