Answer:
Oxygen in hydrogen peroxide oxidizes from -1 to 0.
Explanation:
Oxidation is the loss of electrons. The specie which is oxidized has has elevation in its oxidation state as compared in the reactant and the products.
The given reaction is shown below as:
![5 H_2O_2_{(aq)} + 2 MnO_4^-_{(aq)} + 6 H^+_{(aq)}\rightarrow 2 Mn^{2+}_{(aq)} + 8 H_2O_{(l)} + 5 O_2_{(g)}](https://tex.z-dn.net/?f=5%20H_2O_2_%7B%28aq%29%7D%20%2B%202%20MnO_4%5E-_%7B%28aq%29%7D%20%2B%206%20H%5E%2B_%7B%28aq%29%7D%5Crightarrow%202%20Mn%5E%7B2%2B%7D_%7B%28aq%29%7D%20%2B%208%20H_2O_%7B%28l%29%7D%20%2B%205%20O_2_%7B%28g%29%7D)
Manganese in
has oxidation state of +7
Manganese in
has an oxidation state of +2
It reduces from +7 to +2
Oxygen in hydrogen peroxide has an oxidation state of -1.
Oxygen in molecular oxygen has an oxidation of 0.
Thus, oxygen in hydrogen peroxide oxidizes from -1 to 0.
