Answer to Question #69254 in General Chemistry for Gabriela
Question #69254
In its reaction with potassium permanganate, is hydrogen peroxide acting as an oxidizing agent or a reducing agent?
Expert's answer
5H_2 O_2+3H_2 〖SO〗_4+2K〖MnO〗_4⇒2〖MnSO〗_4+5O_2↑+8H_2 O+K_2 〖SO〗_4
The oxidizing state of O in H2O2 is -1, but after reaction it becomes 0. The oxidizing state of O is decreased, that’s why H2O2 is a reducing agent.
