Question

2 Fe⁺²(aq) + H₂O₂(aq) ---> 2Fe⁺³(aq) + 2 OH^-1(aq)

What is the oxidation state of oxygen in H₂O₂

Answer 1

Oxidation state of oxygen in H2O2.

Since hydrogen has an oxidation state of +1

Then we'll be having;

(1)2+O2=0

2 + O2 = O

Then bringing the constant to the right side have;

O2 = -2 Dividing both side by 2, we have;

O = -1

Therefore the oxidation state of Oxidation state of oxygen in H2O2 is -1
